i get sleep paralysis (which is often real scary-i've had people chop my limbs off and things). but often for those ones i just see really big and weird objects that don't belong where i am. and it frightens me for some reason. even though in real life i would not care. and night terrors and things. i sleepwalk and sleeptalk too. i've carried full conversetions with my husband that he has not realized i am asleep.
i am often "half awake" and "half asleep" even when i am not dreaming. the slightest sound i am jolted awake and completely alert. i've woke up: making ramen. in the bathroom. on the lawn. in the closet covered in blankets... one time i woke up at work!

but the night mares/terrors which unfortunetely include elements of my traumas.
what works for me is probably distinct. because my issues are probably
not ptsd related. it just so happens that i do dream a lot about my trauma. (whereas night terrors are destinct and i usually don't remember any thing and they usually cause more distress to my family than to me!)
the best thing i've learned to do is recognize when i am asleep. if i am dreaming. and that can happen as long as it isn't a night terror. you
can gain awareness. and wake yourself up. you actually don't even need to go as far. as changing what is happening in the dream. knowing that you are asleep and then forcibly waking your self up. is much faster and easier. you probably will deal with the nightmare again. as it isn't dealing with it. but that's what i do when i cannot be fussed.
i can do this as well as i can normally control my behavior. and by thinking the same things over and over again. i can effect what the dream is doing. but that takes effort. and i want an immediate solution. so i wake my self up. because the effort of doing that is not there. when i am dreaming about
my dad going on a meth binge. and i am restrained and terrified.
those happened f*cking
constantly in may and june. so i just started waking my self up. usually with clapping or banging on something. or stomping your foot or some other action. for me clapping is what works. that's hard and it takes a lot of work. if you don't actually
have any dream awareness.
getting it is difficult. but it is possible and people do it all the time. and it's the single most, simplest, thing you can learn to do. when you're like that. to wake your self up.
if it's a
night terror this is different. if you remember what's happened then it isn't. but if you're thrashing around and screaming and being really aggresseve, that
is a problem for the people around you. when that happens to me i usually cannot be roused. and if you yell at me or try a lot it will make it worse. because my brain isn't f*cking on.
so waking your self up will work.
if it's a nightmare or a sleep paralysis episode. if you're on other medicines that can cause adult night terrors or other parasomnias then you are looking at a different problem. because i am so easily aroused it often does not take long for me to be woke up any way. if that may help for you to have any one around. that can wake you up quickly.
the sooner i am pulled awake from it the better things are. some times i only have one or two a night. some nights i'm totally fine! for years i
was fine. and usually i didn't have nightmares. (but i did have night terrors and sleepwalking). the other thing i do is to turn on all the lights. and get a dry blanket. and maybe play some game on my phone. or talk to my spouse.
