Hey! Going to reopen this one.
Currently on day 5 of sobriety and I'm experiencing this. I've come off of alcohol many times and it's never happened.
I have a program on low volume and the fan on, trying to fall asleep and all I'm hearing is a very low music which I can only desceibe as the start up music to classic Disney movies... it's so so strange.
I'm also having a visual hallucination. I have another doorway in my room and I'm convinced someone keep peeking around the corner at me.
Freaked out, but also pleased that this seems to be quite a regular occurrence.
