Dream of person, roof, uncle, woke up, caught

I started out at my uncles house ( wasn't his real house ), and i was playing with my little cousins. Me and my cousins were having fun and everything but then i went to this room. This is were the dream went from normal to what ever its supposed to be. So now from this room i look out the window and i see this HUGE house ( in this dream my uncle's house was big but not as big as the house across the street/ and im not sure if i saw a person or not at the house across the street) . Then i see a door and the door takes you out to the roof of my uncles house, but then i look up and see the sky and it was pitch black dark, full moon, stars everywhere ( felt like the sky was right in my face ). I get a feeling in my gut ( because i'm scared of height's ). I tell my self not to go out onto the roof but im even hard head with my own conscious so i try to go and it was like i was about to fall but i caught my self ( the sky got bigger then). I did the same thing again and the sky gets even bigger. I did it one more time and the sky gets bigger, like the moon is right in my face and im holding on the the door trying not to fall into the sky and then i woke up.
