Nightmares/Nose bleeds

I’m 17 right now and for a majority of my life, I’ve had frequent nightmares. For the last two and a half years or so, I’ve gotten nightmares every time I’ve gone to sleep, leaving me tired every morning. I’ve just woken up from one with a bloody nose, so I’m sitting in the bathroom cause it’s still bleeding. I realized that after new nightmares that I haven’t dreamed before or after the worst ones, I get really bad bloody noses. I know these are caused by stress/anxiety. Do any of you have the same problem and if yes, then how do you deal with it?
