I've not heard of a flashback lasting hours.
Mine have, and often do.
I’ll walk around smelling smoke, or CLP, or JP5, or burning sewage, etc. for hooooours. Drives me spare. Especially when it’s somehing I could reasonably be smelling, now, like certain kinds of smoke (it smells like an electrical fire up in this bitch, is a lot more concerning than smelling pop smoke). I have to chase all over the house/building/etc. trying to figure out if something is
actually burning, hands along walls feeling for heat, or if it’s just a flashback. Some of the unreasonable ones, meanwhile, like burning bodies? I’ve had to actually sit myself down and explain to myself that the neighbors
may be BBQ’ing, but they most certainly gutted and cleaned whatever it was, first, rather than cooking up a steaming mess of entrails and shit and blood for dinner :wtf: Makes no sense, right? And yet I’ve had to talk very sternly to myself to keep from popping off at the neighbors. It’s not them. They’re not making this smell. It’s not them. It’s me. <<< I carry camphor around with me in my bag, not because I need it for real life, but because it’s distractingly strong when past lives start calling.
Tooth pain is another one thay drives me batty, because it could be I’ve actually broken a tooth, or have a wicked sinus infection coming on, or phantom pain (it’s not a whole limb, but I can frequently feeeeeeel parts of my mouth that simply aren’t there & my tongue confirms nope that piece of my jaw is still gone), or flashback. So I have to source that business out. Upside? If my teeth are fine, and it’s not missing parts of my mouth, and my sinuses are clear? That particular flashback tends to herald 2-3 weeks of symptom spikes coming hard and fast. So as long as I’m physically able I can start to bleed stress like a motherf*cker, take time off for a planned isolation instead of a reactive one, etc.
I have no idea how much of my emotional dysregulation is flashback driven, or A-Z. I suspect it’s mostly from other sources, but? I know that I’ve woken up from a flashback style dream (this is where nightmares belong! In bed! Asleep!) with no emotions. Which is exactly the place I was operating out of, at the time. That one lasted a few weeks. Other times I’ll be all but knocked down by a firestorm of rage, that I DO need to lay down, close my eyes, and just let it burn itself out (or bad things happen). That’s hours at the least, and has lasted days. A much shorter run is when a multisense movie style flashback happens (moments, of that, usually) and 1 or more senses carry on even after the rest quit. “Stragglers” usually persist for a few minutes up to maybe an hour or so.
Emotional dysregulation is tricky as hell...hell emotions themselves are tricky. But it makes sense that if I can smell smoke for no reason? I can feel things for no reason, too.
