Ive been having weird dreams?

Basically, I've been having these weird dreams where, well they're not really dreams, but when i'm about to go to sleep I kind of think of these things where people are shout or screaming really fast and its really scary for like 30 seconds, and then it stops and it's so hard to explain, but it makes me panic? I hate it, how do I make it stop? I woke up in the middle of the night with it once and I started crying and my mom came in and asked me what was wrong and I said everyone was shouting really fast and she was really confused? I really dont get it, please help :(
