What if you had a recording and headphones set to say "This is a dream" or something of the sort about every 10 mins (Hour, three hours... whatever)? Would this some how help induce a lucid dream, or would it just fuck with your head, like (Keep in mind this is just an example, and not an actual consideration) that episode of dexter's lab when he wanted to learn french and it got just on "cheese omlet" in french, and that's all he could say when he woke up.
