i get lucid dreams regularily. sometimes ill want to wake up from my dream so when im dreaming ill hit myself in the face, scream to be let out, and yell at the people in my dreams to let me out. then sometimes colors will start swirling around everywhere and ill hear this humming sound practically going through my brain. and then everything goes all black and the humming dies down. after that everything is all quiet and i get scared because i cant see or hear anything.

what is this? it happens a couple times a month.
