i think its astral projection but its painful and accopmanied by sleep paralysis and lucid dreaming

I am used to experiencing sleep paralysis. It happens so often that it doesnt scare me anymore. sometimes i let myself stay stuck untill i feel suffocated and i have to move. quite a few times my lucid dreaming has turned into sleep paralysis and here comes the odd thing. I can have several episodes of sleep paralysis in one go. I can get myself out of the state, fall onto my other side but then get it again. These happen between seconds of each other. The only way to get rid of the is to sit up for a few minutes then go back to laying down. However, I think i have experienced astral projection during this time. I feel myself being lifted up for a few seconds: almost as if I'm using a rope to get out of my body. Then I get this really bad headache and return to my body and sleep. The furthest I've ever gotten in that state is to my room door before the pain in my head got really really bad.Can anyone explain this or their opinion or whatever thoughts
