Nightmares??

I am literally having the worst nightmares of my life like I'm waking up crying. I did not go to bed mad or upset. I was not stressed out. I don't know what to do about them. I've had them every hour, this last one was twenty minutes from the last one and the worst so I'm just gonna not sleep this is horrible. If anyone has advice that would be amazing. I am 16 w 1d and take no sleeping meds. Please help
