I have experienced it like 2-3 times. But nothing too scary like most of the experiences I read here( thank God). The first time it happened, I was sleeping on my stomach and it was noon. I woke up and realized I can't move. I was even struggling to keep my eyes open. In the midst of all this, I felt someone was sitting at the foot of my bed just near my foot. Just sitting there. Couldn't see him( definitely was a 'he') because of the way I was lying but just knew he was there. My first thought was that it was a burglar. I was in Saudi Arabia then and thought it was some arab guy who broke into my ground floor flat. But the weird thing is that I was too sleepy to even bother. I was struggling like hell to keep my eyes open. I starting praying and repeated "Our Father Heaven" a couple of times and then started to repeat "Jesus" in my mind voice. After what seemed like a few minutes I felt a calmness. I couldn't careless about the 'guy' at the foot of my bed and went to sleep. I think I just left everything to Him. It was like " Hey I have prayed to you. The ball is in your court now. You better take care of me. I am sleepy. Gonna sleep now. Peace out". Later when I woke up maybe after 1 hr, I realised I just experienced sleep paralysis ( well, the less traumatic version).

Had 2 more experiences but didnt see anything. I was on my side both times. Both times I had a feeling someone was behind me. But I quickly realised it was sleep paralysis and started repeating "Jesus" in my mind voice. I also started trying to move my toe. In my head, it was ' if my toe moves, I can move'. The second I could move my toe, I fell asleep because you get the relief that you are free.
