I posted this on a guitar forum for opinions/experiences, and someone suggested this forum as well. I'll just copy and paste what I wrote. it's very long (sorry) and I wasn't sure exactly where to post this, because it has a little to do with dream control, a little to do with lucid dreaming, and a little about general sleep, and dreams. Anyways:

First off, I've been trying to be able to lucid dream, because the idea is just awesome. I have gotten to the point where I can remember at least one dream every night. I haven't remembered a dream in like the last year, to be honest.

Anyways, I always sleep to music (I'm sure many people do), and I have a giant playlist I like to skate to, and I put it on shuffle sometimes when I sleep. I've noticed a lot of times the last part of the dream I remember has to do with a song I was listening to. For example, last night, I had a dream I met some chick (don't remember how) and we were taking a walk around my neighborhood. Then all of a sudden, I could hear "Invisible Kid" by Metallica playing (go ahead bash me. It's a great album). As we walk closer, there is some band covering that song on the stage by the neighborhood tennis court. We watched a little, then she had to go home, etc. I don't remember anything much after that. After I woke up, I was thinking about the dream/remembering what happened, and I was wondering if I was listening to Metallica at night. Well, my ipod was playing some other song from the playlist, but I hit back, and the previous song WAS "Invisible Kid." Now, that's not the weird/cool part. I was thinking about how many people/studies have shown that music can alter moods, especially when you sleep, thus, altering your dreams. Well, if you ask me, 'Invisible Kid" is a pretty angry sounding song, and anger isn't typically what you would think of in a romantic first encounter with someone. The dream was a very happy one, and I kissed the girl I met, we were planning on hanging out the next night as well, etc, and everything was very happy/romantic. Do sounds you hear while you sleep actually affect your dreams/mood or do you just hear them? (without them having a real "effect").

Do you think if you played a long audio clip of one person talking (in a conversation, but with the other person muted or something) you would respond to the dialogue in your dreams? It would be strange if the next thing the person says has nothing to do with what you say/if they cut you off, but would it almost control your dream? Now it could be like the opposite of a lucid dream, where the dream is controlled by outside forces (like noise). So, do you think lucid dreams could be made easier by selecting certain noises, songs, words, audio clips, etc. and playing them at night? Or would those sounds control the dream?
