My dreams

In movies they say dreams come true right? Well they aren't lying. With my dreams it can be scary. I have dreams sometimes. Usually every night its just black in my head. There's nothing. I wake up and I feel eh. It's been happening for years. I do have dreams but they are rare. When I have a reoccuring dream, it comes true. Say if I got into a car accident over and over again. More than five times at least. The dream will come true. I had a dream a year ago that I had for years but I never knew why. It was my step dad, getting shot by something. (My step dad was an awful dude, he abuses woman and he is a child predator). Anyways, he was shot and killed by a police officer because he pulled a gun on the officer and had drugs with him. He tried to make an escape but the police shot him. We were told right after and I was shocked because I wrote in in my dream journal. I get scared every time I have a dream. The lastest dream I had was a month ago. My dog was put down. I'm not sure and I hope it was a false alarm. Any opinions?
