last night i could hear gameboy tunes while half-asleep xD
About two weeks ago I was lying in bed with my mp3 player on “sleep” and then the song “Lucy in the Sky with Diamonds” by the Beatles came on. 
I’m not sure why, but almost as soon as it started, I don’t know, it sort of started being illustrated in my head with HI. The song felt like it filled every part of me and I could literally see everything in the song happen in front of me, just like in a dream. It was awesome. 
Then when the song finished I slipped into an LD and while I was looking around I saw a picture of Lucy from the song with the river, sky, and tangerine trees. I drew the drawing I saw when I woke up the next day. I had another WILD the same week and that was even weirder. 
(I hope this counts for this topic, it was sort of a music induced LD. 
)
I also often hear music while falling asleep and during dreams, but I rarely remember how it sounded when I wake up, just the feelings it gave me.
to the topic: I have heard sth that happened to you:
A friend of me is very good at the guitar, everytime i go to him i listened an hour to him. One time he played sth. very good so Í asked him from who it was, and he said, that he dreamed tonight that he was a star. He was playing this song in Dream and remembered it, and the song doesn´t exist in real.
