Dreams during pregnancy

Ok, so we all know dreams are really vivid in pregnancy. They can get pretty weird too. With my first pregnancy I had dreams of breastfeeding multiple kittens, birds And pretty much revolved around animals. This time aRound, though....omg. It's straight up NIGHTMARES. I've had dreams where my father in law was shot and killed in Syria(?!) and my husband fleeing from there trying not to die. I've had dreams where my baby died, my mother died and last night, I had the clown from IT come to me at night holding a knife in his hand!!!!!! It felt so real and I felt my body paralyzed from fear as if I were drugged. There was blood everywhere from the person he killed next to me (not sure Who it was) then I saw the clown inching closer and closer until he got so close that he raised his knife and struck me. That's when I woke up sweating and heart  racing😰 I can't take these nightmares anymore, why am I having them?!
