Follow-Up:
I've beein experiencing sleep paralysis with vibrations and some other feelings since I was probably seven years old. I admit it is a very bad feeling, but try to experiment with it. Do not be scared, nothing is going to happend to you or your body. I have it almost every week and you can rally experience some amazing things while having that condition. just never forget that you are in control of it, if you want you can concentrate on your fingers and move them, that's what i do to come out from paralysis but it's better to follow that feeling and you can fly where ever you want and see some strange interesting things. good luck.
