Haunting nightmares

Have you ever had nightmares that kept haunting you for a long time? I've had a few of those that kept haunting me for years during my life and I think the one I've had last night is one of those, too.
When you wake up in the middle of the night, confused, anxious, agitated, disoriented, caught between being asleep and awake and you can't really tell reality from dream. That lingering echo of the nightmare has its claws dug deep into the nape of your neck and keeps doing that for hours, days. And this feeling of uneasiness and discomfort just won't go away. You're still having that nightmare while being awake because it never really lets go.
I fucking hate that.
