You listed music as a possible auditory hallucination? I do not hear "dragging" sounds or anything but I definitely have music playing in my head all day everyday, from the moment I wake up usually. I never considered it to be a hallucination. When I'm not doing anything, it plays in my head so clearly that I might as well be listening to it on an ipod at low volume. It can be great..but equally as annoying, if it's a song I don't like!
