Gave blood.  I knew if I got up that I would faint but the nurse made me move to another seat.  I made it to the seat but then I took a nap.  That's what I call it.  When I was coming back, my eyes saw light and shadows of people but everything was wayyyy blurry.  The voice in my head told me to wake up because I knew that I had passed out but for about 8 seconds I couldn't move nor get my eyes to focus.  It's wierd.  You know what's happend to you but you can't react to stimulus.  I kinda miss it.

It is sleep paralysis..and I have had them for quite awhile. They can be scary but are completley harmless and it is acutally a sleep disorder. I seem to get them more when I am stressed out about something. And just to give you another piece of advice...sleep paralysis almost always happens when you are lying on your back.   Try sleeping on your stomach or side.

scary!!!\nthey could have been just being jerks trying to scare you on purpose. they could also have really meant harm to you. \n\nyou never know the intent in a situation like this until it happens.\n \ntry to stick to places that are well lit and close to houses and businesses. also if you can afford it, get a cell phone so if it happens again you can call for help.

It freaked me out also.  Couldnt move, couldnt do a thing, couldnt even talk.  Just freaking out in my head as I felt this weight on my chest as well, slowly crushing me.

Innocent bystander: You are scaring me.

Ah ha. I used to have this all the time. You are sleeping or falling asleep then suddenly you can't move at all, it usually happens while on your back. It is very frightening at 1st and to me have been more nightmarish but I later read a book (sorry I can't remember the tittle) the author believes they are our like out of body experiences. I found that very interesting being that in all my sleep paralysis, my dreams were super real like meaning I could see the room around me without distortions. If you learn to control the paralysis feeling and go with it without being fear you will supposedly leave your body sleeping and you can wander the other realms in your spirit body, the book claimed.

Hi! I have experience sleep paralysis also, and found it a very frightening experience.  Some people tend to call it 'old hag' syndrome..  others just refer to it as a sleep disorder.  Like you, I rarely said anything about it because I thought I was going crazy!  Check out website www.sciencenews.org/articles/20050709 it's called 'Night of the Crusher', and might help you understand a little bit more.  I assure you that you aren't going crazy or anything.  If it happens again, try to relax and let it all pass.

Being out of control or in the possession of an unseen unknown force.

Well, not that this would answer your question directly, it reminded me of one of the freakiest things that ever happened to me.  My best bud from high school was with me at some orchestral event for some sort of choral competition --I know corny but whatever.  Anyway, we both propped our legs up and were snoozing in the balcony.  I had this dream where I got into an elevator and there were some random people.  We went up a few floors and when the door opened my buddy was there and stepped in.  Anyway we're joking around in the elevator when this lady starts chastising us about being rude and right in the middle we hear the cables snap and the elevator start falling out of control.  Then BAM, I wake up out of the dream with a scream (which pissed a lot of folks off becasue we were at the concert) and I realized that my buddy woke up at the exact same time.  He turned to me and said "Were you dreaming about the elevator?"  And we were freaking out and ticking off our neighbors for the rest of show.  \n\nFreaky as crap but true.  I made some notes to work it into a screenplay of mine but I swear it really happened and I'm not usually the gullable or "spiritualistic" type.  You've inspired me to start looking into if other people have had similar experiences. :P

You should get it back eventually...you may want to consider seeing a doctor especially if it was a hard jolt.

hi........you are describing what me and certain members of my family have had happen many, many times. you are just getting ready to drift off to sleep but you are very much still aware of your surroundings. all of a sudden you feel like you can;t move your body and your breathing feels funny. most of the time we all get the feeling someone or something is in the room with us and it sets such a fear inside you but you can't move or speak. often i try to shake myself awake, but i feel paralyzed. i heard this is a real disorder called sleep paralysis. wow......it seems funny seeing you ask about this. for a long time i thought only my family had this.

When I was 16 years old I woke up from a dream feeling frightened and I saw an apparition like you describe straightening up as if it had been bending over me. I tried to move but I couldn't and it walked into the other room and I heard a rustling noise that I thought was some papers on the table in that room. I was straining to move. I thought maybe it was my cousin who had the room next to mine up on the third story of the Victorian house I was living in. Suddenly I jerked free and I got up and walked into the other room but no one was there. A room led off from that room into a storage room that had a hatch that was open to the summer night sky. As I thought about the rustling noise I wondered if instead of it being papers maybe the noise was some creature with wings flying off. I shut the hatch and went back to bed wondering what the heck had happened. I couldn't tell you what you are seeing. I just relate my story because it sounds somewhat similar to what you describe.

I read somewhere that it is because you are not positioned well while sleeping, so then the nightmare happens so you will wake up and move.
