I had experienced it before 2 or 3 years..In day time itself, I was alone in my parents home, I slept on the couch, I heard like the door bell was ringing. I got up , you know I got up in the sense, my body is lying there itself on the couch, I don't know how to explain.. I got up, reached the door and tried to unbolt it,.. my body still lying there.. I did not understand what to do..i was clueless.. was unable to move my body . I felt completely detached from it. I don't have any power to move a finger atleast . I thought finally, 'ok let it sort by itself.. I'll see what will happen.. I just came and slept on couch on my own body. After some time, my body woke up.. I got up and unlocked, opened the door.. by that time there is none.. however it might sound, I did this and I did not share it any when . I was stressed emotionally at that time, was completely stressed out with some issues,. I used to experience sleep paralysis a lot at that time..
