Nightmares

I wanted to ask if anyone else gets very intense nightmares associated with their fears? I have very graphic nightmares where I have to kill the ones I love to progress to the next level, or me and my family have to kill "fake" versions of my friends and extended family to survive. I also often dream that I'm cheating on my boyfriend, or about people pointing out that I love him less than he loves me. My dreams have always been very intense and vivid. I used to lucid dream a lot too. Still my dreams also used to be more frequently good, with amazing landscapes and fantasy stuff. But for a while now they are at best anxious and more often than not about death, loneliness or me being a bad girlfriend. I hope I can stop having these dreams, it ruins my mornings as I try to stop thinking about them.
