This could be considered an inception or Déjà vu. Maybe it means nothing.
I'm not a professional musician, neither a virtuoso guitarist.
Lately I started to notice/realize that during the very thin line between sleeping and being awake, I'm starting to compose some music in my head. The music that I'm hearing in my mind is nothing like what I hear before. Or maybe my brain is playing ticks on me :)
Once I try to force myself to wake up and try to remember what I was hearing, everything vanished.
Have you encountered this before? Is a symptom of being thinking in music? or just brain's gibberish?
Sorry but couldn't find a better tag
