Once when I was a young teen, while I was waking up from a dream I started to have this auditory hallucination of this macabre classical piano piece I've never heard before. It freaked me out. I was half in sleep and half out. But it scared me because I couldn't make it stop for like 3 minutes. It never happened again.
I used to listen to a lot of music when I was younger and I would play songs I liked over and over again. And when I wasn't listening to my favorite song at the moment, I would sing or hum it to myself, either out loud or silently in my head. The current term for this phenomenon is an "ear worm."
But I don't listen to music anymore very often. I was first exposed to music probably in my first few days of life. My father was a weekend musician and had a band.
