I have normal nightmares, I have nightmares that are crazy blends of reality and fiction, I have nightmares that are real life happening differently (I have died I don't even know how many times, how many ways... Or right people, wrong place... Or right place, wrong people. I drag family into places they don't belong all the time), I have pieces of reality nightmares (like a single sense: tasting blood or feeling pain, or smelling god knows), and I have flashback style nightmares that are reliving the durn thing. I like those. I prefer flashbacks while sleeping. Much less of a pain in the ass than while driving.
How I respond to them varies.
I don't think I've acted out my nightmares in a long time. I rarely thrash or scream or hit/kick blindly these days, either. Used to do both a lot. I often wake up soaked in sweat. Change the sheets, take a shower, and wake up soaked again. Change the sheets, take a shower. I often wake up not really "here". While at my parents I've been woken up with pills being out in my mouth, because I'm whimpering and crying and writhing and shaking in my sleep. Oh. I cry in my sleep. Hate that. Better than while awake, I hate crying and avoid it as much as possible... but man oh man do my eyes hurt. I've woken up with cracked teeth, split knuckles, cuts in my palms.
I also sleep like a brick. Dead to the world, and not even a twitch. Regardless of how violent my nightmares. Sometimes a mosquito farting a block away wakes me up. Sometimes you can shake me and shake me and not wake me (my mom has a habit of taking my pulse, cause when I'm not even twitching, I'm also barely breathing / apparently look dead).
Sleep is weird.
