I was military at that time. We just previous day had marched 60km and i physically really tired but mentally very alert.
As the night came we had to go to sleep and as soon as i hit the bed bam! i felt this complete wave of full relaxation. I wasnt mentally tired but physically i was so comftrable. I started to feel that my bed was spinning and then felt that my head was expanding. I felt like pac man and suddenly my awareness started to move from my body to that huge head. Then i felt strong pull like i was leaking out of my body and i just started to little by little saw our room. I saw my military friend closer than usually from my bed and i looked around and i was all most in middle of our room and saw my body laying there. This freaked me out and i snapped back to my body. It felt real. I really thought it could have actually been my consciousness leaving my body but i cant be sure from only that experience. I was mentally really awake all the time there was no lapse in my awareness and i didnt mentally feel even for a moment that i was about to sleep.
So when i was back in my body i tried to look around and here were something really scary happened. I was at the bottom bunk and the whole room was really dark i look at side of me and i fucking saw hand reaching for my face and near the cabinet i saw face peeking at me. I tried to smack that hand away but it went right trough it and i realized it was hallusination and closed my eyes for a sec and it was gone. Thats it.
I have a lot of crazy experiences like this from military because excaustation and lack of sleep cause really funny things.
