What do these mean?

I'm just wondering what it means if these things come into your dreams:

Made up people
Real people that anda don't know very well
Death of other people

Also I had these two dreams that I want to know what they mean. In one of them I was trapped in a small room with 4 other people. There were people downstairs that were going to kill us. when I tried to go down the stairs the bottom half wasn't there. then we had to go through this hole in the floor to escape. One of the boys refused to go because there were bats and he was afraid of the dark. A hand reached out and started trying to pull us into the hole. Then I woke up.
In the other dream there was a person there and he seemed sad so I talked to him. we started to become friends and then he started to like me. I don't remember very much of the dream, but I do remember walking into a small sheltered area with a black roof and a black bench. It looked strange and slightly tilted and it was black and white. That was also the first dream I ever had that I had a shadow. I also remember this weird permen wrapper that seemed to mean something.
