The latter condition seems innocuous enough: you get arbitrary associations between different sense and higher-order processing channels, and life is a bit more colourful for it. But combined with OCD, I think it makes things a little harder for me. Typical of obsessions, I get into these intense cycles where I have a "bad thought" (e.g. gore images, a cognitively dissonant [fabricated] memory, an unlucky symbol), which must be cancelled with a "good thought" before anything can continue (e.g. the figure of the buddha, an ego-affirming memory, a lucky symbol). Apart from that though, these dichotomies tend to bleed across sensual association space, so maybe I start by obsessing over an embarrassing encounter with a friend, but then it starts to change, it's about the road we bumped into each other on, the grammatical structure of the sentence I used, the numerological significance of the date and time. And by the end I'm devoting my entire mind to worrying about some utterly meaningless chain of associations. I've spent weeks not being able to look at certain shades of pink without panicking. It's like I'm lost in this disgusting network where everything seems connected and mixed together with everything else, but not according to any rational principle, or with any relation to the world outside of my own head. Sorry for the moaning, just need to let off some steam.
