Hello All

"I'm not sure how to explain this so bear with me please. I was laying down and facing my wall on my right side. I do not recall even going to sleep only feeling sleepy. Anyhow, as I lay there I was looking at the wall when all of a sudden I heard what sound like the back of my head starting to crunch then a sudden pop. I recall jumping up thinking I had been shot thru the wall or something heart racing. As I felt my head there was no damage or bleeding then I looked at my pillow and seen it was still dry shall we say. I do not know what happened or why my ears heard it and body reacted the way it did. I can tell you I have never had anything like this happen before or remotely close to it. The sound was sicking to say the least. I can tell you it seemed to come from the back middle part of my head which tingles but not hurt. Has anyone experienced something like this? If so can you pleas tell me why it happened, and should I just rule it as some sort of unknown power nap dream? Can anyone explain to me how I could have been sleep yet saw myself looking at the wall which meant I was fully awake, I had to be!"
