I've had that happened to me once before. All of it sounds pretty much the same, except it wasnt bright around me, nor did it feel like there were thousands of people watching. I couldn't move, felt paralyzed. I couldn't see shit, I was trying to open my eyes and shit but everything was blurry. I felt as though, and I couldve sworn there was a dark figure in the corner of my eye, but everything was blurry so I cant really be sure what it was. This all happened quick, nothing long term, matter of seconds really. It happened a while back, and never happened again. I didn't think much of it, now I'm kind of intrigued.
