Do these dreams mean something?

Sometimes, I have the weirdest dreams, and I mean WEIRD. But for some reason, for most of my life, I've been having dreams and then they later come true, like one time, my aunt and uncle's old house got destroyed by a hurricane, so they evacuated and I had a weird dream about a white living room, and I was looking at a fireplace, and there were all kinds of knickknacks on the fireplace, but I had this dream when I was 4, before the hurricane happened. Then when me and my twin were 9, we got invited to go visit their new home, so we went and it was EXACTLY like how it was in my dream. Usually my dreams involve something happening, and weeks, months, days, or years later it comes true. It's happened on 10 occasions this year. Also, I keep hearing whispers in my ear when I'm home, and I sometimes see figures in the dark. One time I stayed up late and it was like 11:30-12:00, so I went to bed, well then my bed started shaking, I thought it was my legs since I was still up and excited (I was playing a video game), so I raised my legs, and the bed still shook, it continued for about 2 minutes, then stopped. Another time I woke up and my bed is usually almost towards the end of a wall in my bedroom, well it was pushed all the way to the end of the wall. Maybe I did it when I was sleeping, (I sleepwalk sometimes) hope you guys can help :)
