I have several mild synaethesias:
* sound (mostly music) to texture/touch/feel, and sometimes sound-to-color
* scent to shape/texture
* light to sound (usually just in terms of volume: bright spaces are "louder")
* touch to vision

In my world, the letters of the alphabet have genders... Most of them are Male... although all the vowels are female.
I don't know why.

When I was in kindergarten, we learned about the alphabet via the Letter People. The Letter People were puppets one to each letter and all the consonants were male and all the vowels female. Sadly, Mr. Y was always male and didn't go in drag every so often.

Just because I don't have any synaesthesia that I am aware of doesn't mean that my brain is wired correctly :)

I think "correctly" is a term misapplied to brains chemistry/wiring!

I'm not sure if this counts, but when I'm listening to music I see a three dimensional representation of it in my head. This can be frustrating to bandmates when I say things like "that drum fill needs to be more in the top left, and bring it forward a bit".

He he! I love that you do this - I believe that if this was true before you began playing a musical instrument it is synasthesia, but a lot of musicians develop spatial representation of music based on their instruments. The easiest one to describe is piano players locating high notes to the right and low notes to the left in space.

Number-form synaesthesia, for which I did not have a name prior to following your link. Indeed, it was only recently that I realized that not everybody perceives numbers as occupying specific positions in three-dimensional space. (Dates and times exist in their own spaces; I don't know how typical that is.)

For me, flavors have shapes. ("are shapes"?)

That's the thing. Most of my sensations are what I tend to call whole-body experiences, though they don't necessarily have or translate into traits.

In conclusion, I'm Not Sure. But I'm pretty sure that most of the input I perceive gets routed to multiple sensory departments.

Ooh! This isn't synasthesia because it's pretty conscious, but probably somewhere between a third to half of the time when I'm listening to music I am choreographing dance to it in my head despite not that much dance background.

...and I feel neurologically inadequate as a consequence. Sniffle!

Sounds and colors have flavors and smells.

Pain has different colors. Well, so do bruises, but that's not what I mean.

tastes/scents have colors. not mostly foods though -- like chlorinated pools are chartreuse.

To me numbers have genders: odd numbers are male, even numbers are female. I think this might have something to do with the fact that as a kid I learned Hebrew, which has gendered words.

I have this exact same thing (no connection to Hebrew, though). I actually had a discussion about it lately, and a lot of people said it made sense, though they had never really thought about it. Everyone seems to agree that even numbers are generally female and odd numbers are generally male, though there can be some deviation from that pattern (e.g. 70 feels male to me, 89 kinda female).

Weird...

depends on how loose my brain is feeling at the moment. i almost always have sounds -> vision/shape and often have others.

I definitely have motion → sound synesthesia; I'm definitely prone to hearing things in my mind when I'm visually put in certain situations.
