Coping with nightmares

I am 28w and having the WORST nightmares about our house being broken into and my 2 year old daughter being hurt, falling and breaking a bone while home alone and my phones in another room, sticking my bare hand in a very dirty toilet… i dont know why that last one

Every night I am woken up at 1-2 am by nightmares and then can’t sleep all night. I am so exhausted between keeping up with my 2 year old all day growing a baby and these horrid nightmares keeping me up all night. I can’t get them out of my head. What do you guys do to get rid of the nightmares or go back to sleep? I’ll try anything at this point I just need sleep the less I sleep the worse these nightmares get.
