As a young buck lucid dreamer, I run into my fair share of nightmares (once every two weeks), it always pertains to aliens chasing me. I dream a lot about zombies but its never scary, I actually have fun with zombie dreams (had one a few days ago).
It's not an issue anymore but sleep paralysis was the worst. I never encountered the hag (thanks god), but just the inability to move freaked me out. Every time I break free, I get upset at myself because I know it's the perfect opportunity to induce an out of body experience. I had a couple very successful OBEs! It was intense lol oops sorry I'm getting off topic. I can't give you any meaningful advice because I have yet to conquer my fear over aliens in my dreams.
Weed and booze helps put me to sleep and kills dreaming but isn't sustainable long term or healthy. Wouldn't hurt to try though in your case. I'm guessing you've tried this already uh see a sleep specialist?
