I had a dream last night that I was outside my house with my sister and my dad. They were closer to the house and I was wandering farther, like by the end of the driveway. Then I wanted to have a cigarette so I went inside to get them and then I started walking up the street. I noticed there was a guy in his car behind me, but he didn't look suspicious. Just as I lit my cigarette I looked behind me and he was running towards me so I started to run. I don't really remember what happened after that, I think I woke up.

What does it mean?
