r/Synesthesia

People with synesthesia , what are other things you jave that come with synesthesia . Things like maladaptive daydreaming, ADHD,Autism spectrum traits, etc. Keep an apropriate language and share your experience !

So i know colrs of the yesr show what color is consideres fashinable to wear that year but if you were to chose the color of the year based on the color you associate the number like “2026” what colors would you chose for what years? Like for me
2026-brown
2025-red
2024-blue

Hey ! Even of the post is old like posted a month ago please answer if you want! I was wondering if some people with synesthesia would answer this questions ,please number your answers according to the questions so like 1 - answer 2- answer and only answer the questions you are comfortable about ! Keep an appropriate language
1 How did you even found out about synesthesia ? When it comes to mental knowlege, people think about bigger things like autism , adhd ( not that this isnt important ) but i feel synesthesia isnt as known so how did you even found out about what synesthesia is ?
2 how did you found out you have it ? Did you found odd that your senses mix togheter or that you see colours when hearing song , associate letter with coulours , etc and googled your experience , did someone else told you you might have it ?
3 What type of synesthesia do you have ? Projector,associator,chromesthesia,etc?
4 how do you feel about your synesthesia?

If you would like to talk about other things besides the questions i asked , feel free to say anything you want!

Hi r/Synesthesia. I've been reading the time-space synesthesia literature (Brang, Simner, Smilek, the Sagiv consistency work) and most of it focuses on calendars, either months in circles or years along lines, that kind of thing. I'm more interested in something that is touched upon by the literature, but not extensively, which is the number placement within your synesthetic layouts, over a broader set than the typical 1-10 range of experiments.

I have some questions, if you don't mind me asking. You don't need to answer all of them. Just answer whichever feel interesting.

1. Shape. Does your number space have a general shape to it? The classical answers include "line," "ring," "curve," "grid." I doubt these are mutually exclusive categories. Does your number layout fit into any of these, or do you have something weirder, more complex. Is it bent/folded or multiple segments, is it 3D, does it become discontinuous between decades? What does it actually look like?

2. Density. Are some numbers in your layout vivid while others are dim? Is this arbitrary, is there a pattern (e.g., primes are vivid), are decade markers bright (10, 20, 30, ...), or do personally significant numbers (e.g., birthdays, home/other addresses) get highlighted?

3. Stability under external conditions. Does your layout change when you are tired/stressed/sleep-deprived/on drugs/etc.? Or does it remain stable regardless of external conditions? The question matters, since many researchers assume full stability, and I doubt that's true.

4. Errors. When you make an error involving numbers (eg.: remembering a wrong phone number digit, mixing up a price, remembering a date incorrectly) does the wrong number tend to come from close proximity in your synesthetic layout to the correct one? Or do the errors come from across the layout?

As I said, most of the literature focuses on calendar synesthesia and mentions number space as an aside, but you know your numbers far better than the researchers. I'd be genuinely interested to hear about the experiences in the community!

Thanks a lot.

Mine is that the word “rummage” tastes like mashed potatoes ¯\_(ツ)_/¯

People with synesthesia , what’s one thing people always say that makes you go crazy. Example : math is blue ( maybe for you its grey) . Whats one thing people associate wrong ( in your opinion ) and makes you go crazy ?Speak up about it and give as many examples as you want . Keep an appropriate language.!

I have always associated different colors to different weekdays or letters and numbers, but I don’t know if that is something I learned or something I was Born with. And when it comes to music I have always been for some kind of reason very obsessed with music itself and drawing and art in general. But I don’t know if I really hear colors or if I’m just lying to myself, but the second i heard about this phenomenon called synesthesia i like thought to myself I have always associated different colors to different music and instruments and stuff but sometimes I have to like think about what kind of color this would be, and sometimes I just see like different waves of colors and the different waves of colors are the different components of the song but about that I don’t have to think actively I just close my eyes, I really don’t know. I did different online tests and they all tell me different things, idk maybe I’m just convincing myself to be something I’m not to feel happy or special. But I have always been very lured by music and different tones and stuff. Can you please help me out I don’t know what to do anymore. ? Sometimes I feel like I am really a synesthete and sometimes I feel like I’m lying to myself idk

^(Just found this sub today, and very excited! Hi all : D)

Ok, so I've known for a long time that I have a couple types of synesthesia:

1. Numbers and letters (sometimes full words) always have their own colours.
2. Some music triggers specific shapes and colours.

But one thing I've occasionally wondered about is if/how synesthesia might be affecting my appetite. And I'm really really curious to know if anyone can relate to what I'm about to describe. So, here's what happens...

I can be eating my favourite food, really enjoying it, and quite hungry at the time. But even in those circumstances, it's extremely easy for me to suddenly lose my appetite if I hear certain things. And they're really random things like:

• someone saying a specific word, like 'compost'
• people arguing in a sitcom
• hearing mention of a violent act in a podcast
• hearing even just an ad about medical conditions

It's really annoying but it feels like it somehow takes over my imagination or something, and completely ruins the food. Almost as if I'm eating something foul.

Does ANYBODY know what I'm talking about?

Just a question for those of you who have the sound-to-colour type of thing ^^" I've been looking through this subreddit for a while because I found it cool, but I have a question. Do those of you who have the sound-to-colour (sorry, I'm unsure how to describe what I'm trying to say) version see colors that you get from sound, out in the "real world", or is it more of a "mind's eye" type of thing?

When I listen to music especially, I see a lot of colours in time with the music, but it's mostly in my mind, so I was wondering if any of you who have Synesthesia experience it similarly?

Also, can this be developed, or is it something you're born with? I saw it off of google that you can but I wanted to ask you guys to double check. Sorry for all the questions, I wasn't sure if there's a FAQ or something similar here.

I would make this post a "is this synesthesia" kind of post but it has more questions than that so I will make that seperate probably.

i don’t (to my knowledge) have or experience synestesia; when i have sex, i “feel” different colours and even feel and see items (strange example, reese’s cups). i often also, when experiencing these colours and shapes, feel far away ? and when it’s over i feel like i come back to where i was.

outside of the sexual side of things, i strongly associate feelings and smells with colours but i don’t believe that’s synesthesia, but based on my research, is it possible to only experience it during freaky time ?

Im curious to learn about this phenomenon, can people who experience this please let me know, do you find others with similar types of synesthesia mostly agree with you on your perception of for example the colours of letters or the shapes of sound?

Id love to hear about your specific type(s) of synesthesia, share whatever you are comfortable sharing! ❤️

Not sure if should make a sepparate post for this, but Id love to learn your specific system of what things you combine! (For example, I once had a coworker who told me the number 6 was always pink for in her mind)

I have a 10 year old who recently explained that she sees colors anytime she sees or hears a number. I had NO IDEA this was a thing. She never mentioned it because she thought everyone experienced numbers the same way. She had a hard time explaining. To others who experience this…is a 3 ALWAYS orange or is it orange today and purple tomorrow. How did you discover this wasn’t common?

I have been thinking about this for a long time and after searching extensively I couldn't find any posts or discussions that describe what I experience. I decided to reach out to Reddit and other science communities hoping someone here can relate, share similar experiences, or point me toward relevant research. I am genuinely curious about understanding my own neurology.

When I receive a medical injection, I experience what I can only describe as a "taste" — but not in my mouth, not on my tongue, and completely unrelated to my mouth at all. It is a direct sensation inside my brain itself. The best way I can describe it is that each medication has a completely unique chemical signature that my brain perceives and memorizes. When I receive the same injection again later, my brain instantly recognizes it — not by name, not by appearance, but purely by that internal sensation. It is like my brain has built its own private library of chemical fingerprints.

More broadly, when anything changes inside my body — temperature, pain, a chemical entering my bloodstream — my brain receives what feels like an encoded signal. I immediately know what it means and what is happening in my body, but I cannot translate it into words or explain it clearly to others. It is like receiving a message in a language only my brain understands. I can read it perfectly but cannot teach it to anyone else.

On top of this I also experience:

Extremely high pain tolerance. I had surgery and felt no pain during or after, while others who had the same surgery reported constant pain.

Precise internal temperature sensing. When I have a fever I can estimate my exact body temperature and I'm usually accurate within 0.2 degrees.

None of my family or friends experience anything like this. Has anyone experienced something similar? Is there any research on this? I've found synesthesia research but nothing that matches this exactly.

Important clarification: I am NOT talking about the common metallic taste in the mouth that many people report after injections. This has absolutely nothing to do with my mouth. It is a sensation that occurs purely and directly inside my brain.

Note: English is not my first language. I used AI assistance to help fix grammar and express my thoughts clearly.
