A really annoying thing that started happening to me is that I will be having a nightmare and then realise it's a nightmare during the dream because I suddenly can't speak or form words. And I slowly feel my body start to go numb. And that is definitely a sign I'm about to wake up and be in sleep paralysis. If I can wake myself up in time, I don't experience sleep paralysis but I get the full body tingle thing which is so uncomfortable.
So of course I make my MCs suffer the same thing. LoL. If I have to suffer it, so do they! ╰(*°▽°*)╯
