Almost every night that I go to sleep, just as I am about to fall asleep I am jolted awake by what seems to be a 1 second nightmare.

Just as I am about to nod off I dream I've been hit by a car/ hit in the face with a bat/ fallen off a building/ fallen out of bed/shot at/ etc. As soon as this happens I wake up but then within 1-2 mins I'm fast asleep.

Is that weird/normal?????
