I was trying to go to sleep last night. I must have been asleep for 10 to 20 min. Then I am woken up. I feel like there is a presence and there is pressure on my chest. Like somone is getting on top of me. I wake up and scream "HELP!".

My wife contributed it to me trying to have LD's all the time, but I was not doing any induction technique at the time. I have heard of similar experiences called the "Old Hagg Syndrome" but it is usualy attributed to SP. I have had SP in dreams before but this felt different. Just curious if anyone has had experienced this before or any of you know what this is? I dont think I was dreaming it was too early for R.E.M.
