I just decided to start trying lucid dreaming and studying it and I've been trying to do a MILD for a few days now but, every time I do I start getting itchy. It's not just like 'Oh that itches' its like 'DANG THAT ITCHES!' or a bunch of little itches. Also, I always get a song stuck in my head and it's usually a rock song, and i can't concentrate on paying attention to recognizing that I'm starting to dream and falling asleep. Any suggestions?

Another thing is I usually start going into a dream then get kinda nervous and come back to consciousness. Any suggestions for this too?
