This may sound weird, and i don't know how many people can do this but its really cool. Once im lucid all i have to do is think of a song and it will start playing without missing one beat or word. The first time i did it i was memorized by the fact i remembered a whole song and could recall it perfectly. The second time i got creative with it and try'd to make other people sing the song, and IT WORKED and it was in their voice. What's strange is when I try to sing in a dream it doesn't work, i'll forget the words, although the beat may be right on. What's even stranger is songs i hardly remember play perfectly as if i downloaded it and could play it just as i could on my ipod. Is the mind just that good of a recorder/mp3 player?
