I was wondering how that could affect somebody who is in a dream, or transitioning. Not that I have yet, but...
I thought that when I was going through my iTunes playlist yesterday. For example, what if you play a song that is pretty morose? (My thought for that was "Hey You" by Pink Floyd- give it a listen, you'll get what I mean) Or something that's happier, The Who for example. Would that affect you while sleeping?
