My experience with nightmares.

Hello! This is my first blog entry, and I want to see if people have experienced what I've experienced. So, my experimce with nightmares started after my mom got cancer. She beat it and is fine now, but I think this was where the problems started. They weren't that bad around this time. Maybe two a week.  It all got severely worse after I thought my sister got attacked by a dog. She didn't, and she's fine. I just freaked out. By then, the nightmares had increased to every single night. They were all of people I love being hurt or other such gruesome things. A crazy one was of my mother selling my sister and I. I got put on a temporary med to get rid of my nightmares, but I'm still scared to sleep sometimes. Has anybody else experienced this? What did you do to cope with the fear?
