I've had sleep paralysis on several occasions, in which two of them I had actually left my body and had an out-of-body-experience. It is actually a normal thing, but we usually never experience it. You see, every night our body performs sleep paralysis, but we never realize it's happening. What happens is that our mind sends signals to our body, giving strong urges for it to move; the body can do two things, it will move because of these urges or it will ignore the strong urges. If you ignore these urges, usually you end up with these two symptoms; hypnogotic imagery and hypnogotic hallucinations.
Hypnogotic imagery gives us to see images in our eyelids and hypnogotic hallucinations is were we hear strange sounds, feelings ect. Usually at the exact same time, you feel vibrations all over the body, usually very strong followed by the feeling of pressure on the chest; like something is sitting on your chest. At this point, you are at the peak of the experience, after that, you will not be able to talk, move or open your eyelids; if you try to talk it will just be moans and if you try to open your eyelids, you may see hallucinations. What you see in sleep paralysis, it is all in your mind, there are no such things as demons or ghosts. The experience can be pleasing as well.
When I had my experiences, I interrupted a sleeping pattern called REM (Rapid-eye-movement) which caused me to automatically awaken with full sleep paralysis. I tried to yell out for help but all I could hear was myself moaning, I tried to open my eyes only to see my door at the end of my bed. I knew what was happening, so I exited/separated out of the physical body. 'Astral' Vision comes to your straight away, it's as if your're imagining it. In another OOBE (out-of-body-experience), I had sleep paralysis, exited the body, I wanted to see how expanded I could use my skills, I thought of visiting my aunts house, I spun around in 360 degrees and saw a transparent brick wall... I was in the 'astral' realm, and I was sitting in my aunts arm chair. It seemed so authentic, because the conversations seemed so real, like reality. I was worried I was going to get stuck in this world, and called for home (my body), I woke up in my bed wondering what just happened.
The experiences are really life changing, and people shouldn't worry about them. They are very normal, but sometimes we come face to face with them, and we mistake them for a supernatural happening. On this topic, I have also had several Lucid Dreams, which are basically the same as OOBE's but you induce them through dream state; DILD, (Dream induced Lucid Dream). When I had my morning sleep paralysis, I induced it by DEILD (Dream Exit Initiated Lucid Dream/OOBE). Lucid Dreams are just the weaker consisnous compared to OOBE or Astral Projection. I have been studying dream patterns, OOBE's and Lucid dreams for a year know and the study is interesting. If you have any questions, trust me, personal message me and I will answer them to the best of my ability.
