Synaesthesia – the blending of the senses – is a really cool form of neurodiversity. It involves having cross-wired senses, so that you might experience sound visually or taste colours, for example. The sensory combinations are quite limitless, and most are poorly researched, and difficult to validate because the synaesthetic experience of each individual is not necessarily the same. For example, two synesthetes might disagree about what colour the same sound is!
It’s taken a while, but I have worked out that I have at least 3 types of synaesthesia and possibly some others that have not been well categorised yet, but for which there are numerous self-reports available online. Two important things:
- I am primarily an associator synesthete, meaning that I experience these things very vividly and intensely within my body and mind’s eye. If I close my eyes, I can visually see the synaesthetic experience clearly. In my synaesthesia experiences that involve physical sensations, however, I often am a projector. This means that I physically experience tactile sensations as if they were really, tangibly occurring.
- My synaesthesia is consistent – the experience doesn’t change over time. However, not all stimuli provoke a synaesthetic experience. In other words, listening to some music can provoke intense visual experiences, while other songs are purely auditory with no synaesthesia whatsoever.
A synaesthete’s artistic impression of how music looks to her. This is remarkably similar to how I experience sound, although with much more light involved. But how do you paint light, really?
So, the synaesthesia that I experience are as follows:
- Chromasthesia – Sound to Colour (Associator)
Individual notes elicit very little synaesthetic experience, it tends to be a response to tone of sound rather than pitch. For example, certain instruments consistently have particular colours irrespective of the notes being played. Listening to music can be an overwhelming experience, because combination sounds that occur in songs cause me to experience multidirectional synaesthesia. That is, I have both a visual and tactile experience at the same time. Visually, it is like looking at a nebula sometimes, with colour and lights occurring in different opacities and boldness. Voices often occur in ribbons, with female voices being various shades and combinations of pink and golden yellow, and male voices being bold oranges, yellows and whites. To this day, Billy Corgan and David Draiman have THE MOST synaesthetically pleasing voices I have ever personally experienced. Billy Corgan’s voice produces ribbons and sharp lines of beige, peach and cream colours, depending on how he uses his vocal tone. David Draiman’s voice is like light being turned up and down in brightness, and is the most glorious shades of gold I have ever seen.
This song gives me an intense chromasthesia experience, and is one of the most vibrant and diverse experiences of David Draiman’s voice…imagine many shades of golden light in ribbons that are turned up and down in brightness as his voice dynamics change throughout the song. The musical aspects of this song are very bold, dark walls of purple with orange lights dotting it…imagine orange stars in a purple nebula in space.
Other, non-musical sounds – particular nature sounds – cause synaesthetic responses also. The call of the Australian raven is like the blue-black iridescent sheen of its plumage forming three partial funnel-shaped walls with each of the three ‘caw’ sounds made by the bird in its typical call. The walls are three different heights correlating to the descending pitches of each ‘caw’ and join up in sequence to create a full funnel-shape.
- Auditory-Tactile – Sound to Sensation (Associator and Projector)
This is an extremely overwhelming, and sometimes disorienting synaesthetic experience for me. It often results in serious sensory overload when sounds result in negative tactile experience, particularly because they are physically projected onto and experienced by my body. But positive tactile experience in response to auditory stimuli are also incredibly intoxicating at times. Some examples:
- ‘Buzzing’ sounds associated with mass human conversation (like in a food court), hums from fluorescent lights or idling engines, banging or pulsing sounds (hammers, dance music, tapping) all come with an array of unpleasant tactile sensations that range from dizziness, falling sensations, spinning sensations, tapping against my skin sensations, and ‘prickling’ sensations. Interestingly, many of these co-occur with negative chromasthesia sensations, particular bright, piercing light. While I don’t actually see the light, my eyes physically sting and hurt as if someone was shining a torch into my eyes.
- Some music is pure ecstasy to listen to, particularly when the auditory stimulus provokes both tactile and visual synaesthetic responses in combination. In many cases, I actually have major shifts in my sense of proprioception – that is, the sense of where all my body parts are and how they are contained…or in my case, not contained. Music actually makes me feel that I am no longer inside a physical body sometimes, and that my parts are floating in space. If I actually move while this is happening, say for example, spinning in a circle, I feel like my body parts are flying off into space as I turn! It is actually a really euphoric, transcendent experience and makes me wonder if this is what people experience on drugs!
To this day, this song continues to have one of the strongest combination chromasthesia and auditory-tactile responses in me. It is difficult to describe in words…but I will try. Basically, I feel like I float up and out, my body explodes out of it’s container and into space. That space visually looks like a nebula of pinks, purples, turquoises and bright white, orange and yellow lights dotted throughout like stars.
- Ordinal Linguistic Personification (Associator)
Days of the week and shapes have colour and gender. Every word in the English language has gender to me. For example:
- MONDAY/Triangle the shape = Female, however the word ‘triangle’ in totality is male.
- TUESDAY = Male.
- WEDNESDAY/Rectangle the shape = Female, however the word ‘rectangle’ in totality is male.
- THURSDAY/Square (both green, but different shades) = Male.
- FRIDAY/Circle = Male.
- SATURDAY (actually colourless, kind of like being ‘clear’) = Female.
- SUNDAY = Unisex, with male dominance.
Numbers and letters have distinct gender. For example:
- 1 = male
- 2 = female
- 3= male
- 4 = male
- 5 = male
- 6 = female
- 7 = male
- 8 = male
- 9 = female
- 10 = male
a/d/k/m/n/r/s/v/w/y/z are all female.
b/c/e/g/h/i/j/l/o/q/t/u/x are all male.
f/p are unisex, with f having male dominance and p having female dominance.
Some letters and numbers have personality or relationships…for example, the letters R and S have a rivalry based on a shared affinity for the letter T, where R is jealous that S sits beside T. Some letters have unpleasant personalities, such as M, while others are extremely friendly and welcoming, such as B, H and I. The letters A, K and Z are strongly associated with strong, feminine personalities, with Z having greater wisdom compared to A and K.
Non-sequential subjects also have gender. For example, trees and plants have gender that is not species-specific. From tree to tree and shrub to shrub, I can generally tell you what gender each individual is. Certain animals are also strongly gendered…for instance, cats, ducks and whales are female, dogs, horses and dolphins are male.

- Poorly described forms of synaesthesia that I experience:
- Personality to Colour (Associator)
People and their personalities have colour/s. This is usually most vibrant based on first and acquaintance level perceptions of people. The more I get to know people, the less vibrant and more varied their colours become. For example, first impressions are always a single, bright colour. My family members, on the other hand, are multiple colours that are mostly dull with aspects of bright colour and light.
- Smell to Colour/Sensation (Associator/Projector)
Almost all smells have intricate combinations of colour. Biological smells have the most vivid and intense colours and also include mild tactile projections, such as tingling sensations. Weirdly, I enjoy a lot of disgusting smells because of their colour and tactile sensation, and I seem to have a heightened sense of smell (which I don’t think I actually do) because of the synaesthetic associations. Animal smells, plant smells, water smells, flower smells, bodily waste (urine, dung, menstral blood, etc) smells, and raw or decaying meat smells are extremely intense, overwhelming and often pleasurable experiences for me…something that kind of freaks other people out sometimes.
- Visual-Tactile – Sight to Sensation (Associator and Projector)
Intensely visual stimuli (particularly light) cause similar tactile responses to my auditory-tactile synaesthesia. All of my life, I have referred to this as ‘my enchantments’. Things like light on water (rain drops, flowing streams), the orange street lights at night, fairy lights (like on a Christmas tree), sunlight on clouds, glowing embers and firelight, and torchlight on fog all elicit strong, physically experienced tactile sensations. This occurs in combination with a kind of pre-occupation that looks like ‘mindless staring into space’ at the visual stimuli that occurs as part of my Asperger’s experience. This combination of synaesthesia and Aspie experience is sometimes difficult for me to disentangle, because as far as I am aware they have co-occurred my whole life and are one and the same experience. I only know that there are two different contributions because of my Aspie experience also manifesting without synaesthesia in other circumstances (eg – pattern-based ‘enchantments’).
Photographic examples of my ‘enchantments’. As you can see, light features heavily. All of these visual stimuli result in disruptions to my sense of proprioception where I no longer feel embodied, but rather moving about in space., usually in relation to what I am seeing. For instance, the rain-fall image – when it was being experienced in real time – gave me the sense of falling down and forward simultaneously. Fire-light often makes me feel compelled to sway in all directions, not unlike the movement of flames. The sunset sky gave me the sense of floating upward and expanding out of physical containment and into the sky itself. Some skies also make me feel very ‘wrapped up’ or enveloped by their colour and light. Water always makes me feel like I am moving in various ways, and I also sometimes experience the feeling of water flowing over my skin…which is very strange, because it lacks wetness, only movement sensation. The tree with the sunlight behind it is visually disorienting to me, the light moves forward towards me, and I feel myself move forward towards the light, but the tree remains still.
I wanted to share my synaesthesia experiences because I think they – along with the myriad of experiences of other synesthetes – have the potential to contribute something to phenomenological studies of neurodiversity and the sensuous world – both human and more-than-human. More synesthetes should endeavour to find ways to express their blended sensory experiences as best they can, because they are worth sharing! They highlight a sensory world that I believe a lot of other-than-human animals experience, for example, and may give us insights into other forms of intelligence and consciousness that is based on sensory engagement rather than verbal and ‘rational’ thought/communication. The tricky part, though, is finding ways to express synaesthetic experiences accurately, because no amount of verbal description really captures the experience completely. But this could be another challenge for us human animals to demonstrate our particular gifts in creativity, innovation and ingenuity when it comes to problem solving!
