Has anyone experienced lucid dreams,sleep paralysis,or awaken during R.E.M. sleep?

I have experienced all of these, and they use to scare the hell out of me.Since I learned more about this, it's not as frightening as it use to be.I read about lucid dreaming in Omni Magazine,and a few nights later I was having one,it was really scary the first time,but you can learn how to control them.It was something I didn't know we could do.
