Night Terrors, on the other hand, are far more associated with sleepwalking, and the person who has them rarely remembers anything... waking mentally alert / agile / refreshed BUT physically exhausted... as they “just” suffer the physical effects of screaming, running out of the house in winter, and other forms of -sometimes catastrophic- bodily harm.
Thanks, Friday. This has become a little bit of a pet peeve of mine as there seems to be a trend on social media where more and more people talk about having "night terrors" while it's obvious they refer to nightmares. I guess it's the attempt to emphasize just how bad the nightmares are - while nightmares by definition are already bad and not merely a 'bad dream'.
I only know I had night terrors because the first few times hubby woke me up out of it because he didn't know better and he was worried and tried to comfort me. Or because I woke myself up from physical pain because of running into walls/doors/cat trees. They very rarely are accompanied by imagery (I did get hallucinations with mine) and are just nacked flight-response. Your body literally is pumping adrenaline. Unless you wake up and experience that adrenaline rush in a more awake state (where the night terror may flip over into a panic attack and/or your brain connects the plain physical fear response with an emotional one and/or you remember any associated hallucinations), the aftermath is nothing more than a super sore throat, physical exhaustion, a painful knee, and a reshuffled spouse.
Nightmares hardly ever impact me physically but very much emotionally.
I don't get the ruminating-kind of insomnia, but I do get insomnia, and that leaves me just feeling like I was run over by a truck most times and I walk around basically with major jetlag. Physically AND emotionally exhausted, particularly the longer it goes on.
This is in absolute no way meant to diminish your experiences @Roseptsd98. But it matters insofar because on how you'd try to tackle the issue.
For me, regarding the night terrors, a weighted blanked seemed to have helped. It's only correlational still, but I haven't had one since I started using one over a year ago.
For nightmares, I have not yet identified what specifically triggers them (nor have I for the night terrors, but at least I seem to have found a remedy). They're hit or miss, but I think just general sleep hygiene and stress management are one crucial component. And if they're PTSD-made, therapy.
As for insomnia, probably also comes down to what specifically is the main cause for the insomnia. If it's ruminating? Therapy. If it's fear for 1 or 2 to happen (yep, that's a thing, every time I had a night terror I was terrified of getting another one) - well, management of 1/2. If you have insomnia because of PTSD-related fear, make your sleeping place feel safer; this may even mean sleep someplace else.
In my case, I gotta be mindful about medication timing, messing up my inner clock (if I work past a certain time, I'm just gonna stay awake no matter what), but I still have random insomnia bouts out of nowhere. If PTSD-symptoms keep me up, I manage with reducing those fears, e.g. by sleeping with the lights on, listening to an audiobook all night (also helps to keep the mind from ruminating) and other things that make me feel safe. Sometimes that means to just sit it out and sleep during the day. And while I'm reaaaaaaally not a fan of medication, I recently trialed some Melatonin and it did help somewhat.
The really f*cked up thing about sleep disorders? They are tightly interconnected. Sleep deprivation increases chances for parasomnias, for example. Nightmares increase insomnia. And so forth.
As someone who's had real crappy, unrefreshing sleep for forever despite only rare nightmares, I'm really sorry you're struggling with this. I hope you'll get better sleep. I encourage therapy (are you currently in therapy?), re-evaluate your sleep hygiene/bed room layout/ etc., and maybe consider a sleep study.
