Strange Dreams...

Anybody ever have one of those dreams that seem so real, and have so much detail in them? The reason why I ask is cause lately I've been having really realistic dreams, and I actually love it! I seriously can't wait to go to bed sometimes just so I can just dream. Sometimes if I think of something, I make sort of a story in my mind and then it just goes from there when I fall asleep. It's way more confusing then that but whatever. In one dream, I woke up, In my dream, on a strange beach on an island somewhere. I was all wet so it was like I was brought up from the sea. There was a snake chasing me, but when i ran into the woods a good looking young man split the snake in half and saved me. It was pretty cool. For some reason he took the shoe lace off of my shoe to. Not sure what things mean in dreams but that has to mean something cause it was pretty random. Another dream I had was that my family and I moved to a new town, it was like a small town, it sort of looked like my hometown that my parents grew up in. We go there a lot so that's probably where I got the idea from. But there was a foot print in the cement, and i took my shoe off in my dream and and put my foot on the imprint. It fit perfect. Thing is though, the foot print was right in front of a dirt road alley way sort of thing in between to old shops and the same guy from my other dream didn't see my foot and ran it over with his dirt bike. I've seen the same guy in like 3 dreams already. The dreams are way longer then this but I'm just trying to make it long story short. If there's anybody that knows a lot about meaning's of dreams or whatever, it would be awesome if you could tell me something about it.
