Dream! What does it mean?!?

Okay this was more like a nightmare, but anyway, I was at my house and it looked like a tornado was gettin ready to rip our little house away, and my dad was home with me, and then like i heard a noise, and i saw a freaky guy *which reminds me of Heath Ledger in Dark Knight* and me and my dad start running outside and then there were like bookcases in the backyard and then like we started running away from him and we were like separated and then we started getting closer to eachother, then we jumped in a compost pile then it stormed and then i woke up. What does that mean?!
