I recently woke up during sleep paralysis and was feeling extremely intense vibrations all up and down my body like before you have an OBE. They were so intense I thought I was going to fall out of my bed. Just as they were going something lied down beside me and pressed its body against mine, squeezing me tight. After a while this stopped and I fell unconscious. After I came back,still paralyzed, I could feel it sitting on top of me. What does this mean? Did something come to me to physically hold down my astral body? What would do this?
I don't know but I suffer from sp regularly, although not these past couple of months. I felt like I was being raped on two occasions.
Just curious but have you tryed wearing a sleeping mask? It helped me incredibly with my lucid dreaming. I used to fear sleep because I would literally feel these horrible sensations every other night. Is it something you suffer from?
I know what you feel man. That weird creepy feeling when you're about to fall asleep... almost like entering portal to some dark dimension.... Also in these dreams im either in bed not moving (never saw any shadows or monsters) or literally flying around in my house. Also last night I felt the same feeling but this time I saw the train station in my city at night.
it doesn't mean anything. You're looking for meaning in a pile of bullshit. You're driving yourself insane because you believe in seriously strange ideas and a perceived bias against so called "creativity" pampers the idea that your insanity is worth fostering. You aren't special, nobody gives a fuck about diagnosing whatever illness you've concieved yourself of having.
Sleep paralysis is a very convenient state from which to go on an OBE (usually just relaxing and letting go will trigger it). But it is not necessary. You can OBE from sleep or from pre-sleep meditation (in my opinion the hardest).
As for the paralysis itself, you're not in trouble. Your body deactivates certain muscles so that you don't act out your dreams. The diaphragm is not part if these muscles, don't worry. If you feel you're having trouble breathing it's because you're trying to breath consciously (with a set of paralysed muscles). If you relax and automatic breathing kicks in you'll be fine.
If you can't relax you'll just wake up before suffocating, don't worry. It's perfectly natural, but you're usually fast asleep by this point so you don't normally mess up automatic breathing.

Also I highly recommend those forums if you're into lucid dreaming, OBEs and such. No matter your interpretation of the phenomenon.
