For a certain period of time where I was taking large amounts of psychedelics, I was having endless sleep paralysis experiences.
First three were pretty normal as far sleep paralysis experiences go,
The first time, I felt this weight on my chest and a goblin was sitting on me choking me. But somehow, I had enough power of thought to visualize myself reversing the position and grabbing the goblin's arm into a kimura and broke his arm. Soon after I woke back up.
The next two times, I saw the girl from the ring at the edge of my bed and I yelled at her "suck my dick", partly because I was trying to fight it, partly because I was horny. Then I saw this Rainbow Dash plushie sitting on my desk nodding it's head 'no' at me.

From then, my experiences started escalating in terms of intensity. I would experience these moments of sacred geometry flashing behind my eyes with euphoric blasts of vibrations reverberating throughout my head, being sent into different realms. One time, I felt myself being picked up into this UFO. I saw an array of purple lights around me and I could see out into space from a window. I could also hear beeping noises around me as if there were some sort of a computer system running calculations. Shortly after, I felt my body being placed down on what felt like grass and I woke up in my bed.
Another time, I was sleeping at my wife's, then girlfriend, house and as I was falling asleep, I could hear this little girl whispering in my ear, "the bad man wants to hurt you."
Shortly after, I felt my consciousness spiraling up and flying into the air only to get punched in the nose by some sort. I woke up with this very real pain in my nose from that experience. Other times included me feeling like I had gotten tasered in the side, me attempting to get up and push away some sort of energy in the room while in a sleep paralysis state, only to be overpowered quickly back into the bed.

The last time I went into sleep paralysis, I attempted to stop it and found myself spazzing out with my jaw clenched in odd positions and me being unable to control my body at all. Ever since then, I haven't experimented with it at all.
