I think i should share my experiences, It's a little hard to understand what i wrote but please take time and read it
First
I found myself aware, not in a dream but In Sleep paralysis where I can't move. I was trying to awake but I was in sleep paralysis, Scare Blocked my mind and I thought I am dead. After hard trying, I finally got free but found my self in weird sleep position. I slept on my back, Straight and both hands on chest. But I never sleep like this, I always sleep on my right side! So I did that unconsciously...
I Thought maybe it's just an accident and I should forget it.

In my second experience, Few days after first one, Everything was same except the length of that state, I was completely sure that i'm dead so i stopped trying
When I woke up, Before any REM, Again I found myself in that sleep position. I must note that I didn't tried to sleep in that position and these days I can't recall even a scene of my dreams, I just fall sleep and found myself awake without remember anything. So why I can get aware in sleep paralysis without trying?

Third was tonight, I got aware and this time I knew im not dead so i tried to OBE, I didn't completely split, I have never done this before, I saw my room in real time, My room was ordinary but i saw a dark thing standing in front of my window. I was mentally prepared to encounter with these things but not in my room! So i got in my body and my vision from the room fade out.
So, I was in my body and without any vision, Just being in sleep paralysis and waiting to enter a dream then i heard a sound, It was weird, Such as a tribe who yelling together, I felt something is pulling me with every yell, I thought it's the best time to break the sleep paralysis so i did, then i found myself in that sleep position, again.

How is it possible? Is this ordinary? Why i got awareness when i'm in certain sleep position and when I rarely recall a dream!
I don't know what is wrong with me, Even when I got awareness in a dream, the vision is horrible and I can't move easily.
