What does my dream mean?

In my dream it started out with me walking up to my house, only it was in an empty parking lot for as far as i could see. I went up stairs where I made a left to come to a hallway (normal setup of my house). There are two rooms I can go in, my room to the left or my parents' room to the right. I peer in my room to see my sister and my mom having a tea party in this really frilly girly and pinkish looking room. I go to my right and see my brother and my dad playing ping pong, only with pies (I know so random? haha). I remember thinking to myself My parents were getting divorced and I had to decide between which rooms I wanted to choose between. I should mention that I am the youngest of my family. In the last part of my dream I recall looking out a window and having big, green monsters enclosing in a circle around my house. What does this mean?! Its not a recent dream but its one I will never forget and I just always wanted to know the meaning to! Thank You!
