I've encountered weird happenings within my head, and thought it might be related to the condition.

When i'm drowsy, or somewhat stunned, or sleepy (so when my head is non totally "in itself") i start to perceive sounds, or music (for example music i've heard recently) as if it was really playing.

The most peculiar of these happenings manifests when i am trying to sleep. Not frequently i start to hear voices of past conversations, fragments of words, with voices of people i know, mostly. "It was really awesome"; "don't you think so as well?"; "oh! Stop, you!", things like that. In even rarer occasions (it happened very few times in my life, only three that i can recall), these fragments will turn to static, or even screams, which actively hurt my head. When these happened, after a couple of "screams", i jumped out of my bed, confused and with a slight headache.

As i've stated, these things happen impossibly rarely, and they are not -in any way, shape, or form- a problem for me; i just found this interesting, and wanted to share, for fun.
