Have you guys ever experience loud music in your head. What I mean is when i lay down on my bed, and I repeated the music I have heard to myself. Then the volume seems to crank up and I can hear the music in my head very loud like what you would hear in a concert except its in your head. Sorry, That’s the best way I can explain it. It feels good when that happen and I was able to continue listening to those music in my head for a while before I decided I need to sleep, then the loud music in my head is gone.
kind of werid 
I don’t hear loud music in my head, but I have a tendency to hear original tunes in running machinery, especially when driving in a car. I also get it with hairdryers, though. The difference is, it doesn’t really seem like it’s in my head, it seems like I’m hearing it with my ears and it’s inside the whir of the machinery. It only lasts as long as I can hear the particular machine noise, so if I’m in a car it changes tune every time the consistency of the road surface changes. I’ve come up with a few new songs this way!
Hmm I often hear music as my hypnagogic sounds, and it can be very realistic and loud sometimes. Yesterday I was listening to blues/rock’n’roll in my head before falling asleep. But then I woke up a little bit and the music stopped. I’ve heard tons of songs this way, I really like it (and I like noticing it, cause before I’d never even notice and just fall asleep missing out on all the lovely songs).
I’m having it right now…it’s really common with me though, I always have a song stuck in my head that my mind likes to blast (this week it happens to be some Spanish song).
yeah, omega, that’s what happen to me. (you explain it better than I can)
It usually happen to me also when I’m listening to a song before I go to sleep.
