I have a very vivid, wild, id-driven imagination. There is also a general lack of filter, so my mind will often wander off to VERY dark or sexual places. If I told anyone that bit, they would definitely be freaked out.
Anything I imagine looks very clear to me, with the ability to rotate, change colours etc. I can almost see it as clearly as my actual vision.
That said, I've been told I'm not "creative enough" at my last job, whatever that means. Likely because it bore the everloving shit out of me.
