The worst thing is that these feelings are alllllll too familiar. I used to get night terrors a lot when I was a kid and I recognise this feeling, it's the same as after I wake up from one, that same disconnect, the anxiety, the deread, feeling of imminent danger from nowhere, like i'm "lagging" behind my own body when I move, everything feels faintly unreal and numb but even though I'm breathing calm I want to scream and cry and escape.
