I don't know what rem sleep, but the thing I got the other day freaked the shit out of me, I was truely thinking I was dieing.
First of all, I was VERY tired, sleeping in the RV, and going to "bed" at about 5 in the morning. Well as soon a I fell asleep I "woke up" but could'nt move, I could see my brother and feel the things you don't feel in dreams. I had this very warm sensation all over my body, like someone poured boiling water in my veins. The I fell asleep again, only to "wake up" a moment later, but now I could walk and its exaclty what I did. I  fell on the floor and started talking but I couldn't talk so I tried my hardest to do so and I only made a slight sound, like someone trying to scream with a voice extinction. My brother which I saw in from of me then did the same thing. He looked exactly like the white pale little kids in horror movies.
Then, I woke up, Standing at someplace impossible to stand usually because there is a table in the way. I stayed there for at least 20 seconds watching everyone not noticing me.
I Then woke up again, and even though this time was real, I spent at least 20 minutes sitting and not shure If I was still asleep.
I don't want to live an experience like that again, this, was scary. But does someone know what really happened to me???.. I know its hard to explain...
