When I was little, I often experienced a kind of rhythmic vision. I’d be sitting around, minding my own business, and my mind would wander. It would produce an abstract pattern, for example, a ball moving in a figure eight, or somebody saying something over and over again (It was usually something that I had just seen or heard in real life.) My mind would not let go of it, and it took psychological prescedence over whatever else was happening. It bothered the hell out of me, and it took a huge amount of effort to get it out of my head every time.
I mentioned this at work, and it turns out a few people (oddly enough, all white women) have had this happen to them, with minor variations.
My theory is that these are neurological “growing pains”. However, that theory came completely out of my ass. Does anone know?
