Many people here are writing about listening to music before sleep. But have you tried to listen to music IN lucid dream?(of course not with headphones but you begin to listen in dreamworld) It has incredibly power for me, it's many times emotionally stronger as listening to it when you are awake. For example listening to trance(I don't listen to psytranceD) Is probably best choice for me. I prefer some...uplifting trance(non commercial) for example...I am also making music(mainly trance of course) on PC and LD can be(and is!) really nice for inspiration. For those who haven't tried this yet I strongly reccomand!
