@UnstableAndQuirky it's quite common actually, many people have it :) It's really not that big of a deal, at least to me. I only associate colours with stuff... I don't exactly know what, because it's so natural to me that I don't really pay attention when I do it, but I remember I do it with days, some letters, continents (which is pretty weird, I know) and sometimes names or people... And I also associate smells with periods of time and people with animals. It's hard to explain what it feels like because to me it's just normality...
