Every night, Every day, Every dream Everytime I sleep,I have the same dream. it's about my past. In my past I was abused and raped. I was abused a lot by my grandmother, and my sister. 

It's because you had a very bad childhood, and you are really depressed about that, and so you keep having nightmares about your childhood, I don't know why that happens, but it's probably because your brain is trying to tell you something, that's my best guess, but it's ok, at least it's all over now, but I'm sorry what happened to you in the past, hope you're better now
