So a couple nights ago I began to lucid dream and they always begin with a buzzing noise, and I usually cant so much but create light feelings and such. So then I hear myself screamingish instead of the buzzing and i started to shake so i go and feel myself, because I can move really slowly withut waking up and I was shaking. I am pretty sure this wasn't a real dream. But why did this happen? It didn't really scare me.
