Is there a way to avoid getting it?

I’m 21 and I’ve been getting it weekly since I was 14, I sleep very well (8-12hours) and I wouldn’t describe my life as stressful and I don’t drink is there something I’m missing? I really don’t understand why, I’ve mentioned here yesterday that once I had a joint one with my friend too? I don’t even know what to call it. And and sometimes it’s this loop where at least 3 times I’d think I woke up but I didn’t, and then I’d wake up for real wash my face go back to sleep and it keeps happening until I can’t go back to sleep, it’s exhausting and terrifying if I get it one more time I truly don’t think I’d survive it, the thing is they’re not scary as in hallucinations because I rarely hallucinate but the feeling of being paralyzed and sometimes they’re those random nightmares idk how to explain it, I can manage when someone is sleeping next to me because they can feel me shaking or trying to move so they wake me up (I also woke up a few times unconsciously screaming now the whole house is traumatized with me) but I live alone most of the time so I don’t know how to deal with it when I’m alone I feel like I’m going insane
