In late November I crashed my car and rolled it over on the highway, and I totaled it. I was pretty scared and I ended up being fine, no serious injuries, but ever since then I have been having nightmares almost every night where I crash a car in one way or another, and I usually wake up either yelling, or about to yell, and I wake up with this just overwhelming feeling of terror, like it's still happening even when I'm awake. Is this like...normal? It seems to me since nothing physically that bad happened to me I should be "over" it by now, but I'm most certainly not. So any help is appreciated, especially from those who maybe have had a similar experience.
