What does my dream mean to you?

i had a dream that everyone from my grade were outside at some place and we were all running on like wood built over water and it was cloudy. we reached some huge crowd of people for a charity walk/run thing and it was called "walk for haley". we then ran to some ginormous roller skating rink and some of my friends rollerskated. then it was time to leave and random ppl and i were all in a tiny room and there were some guys that were talking about the end of the world. they were creepy and said "when the end of the world comes there is going to be darkness 2 times" then the room came dark and you coldnt see anything at all except a light on some guy that they killed on his temple. then the lights came on and some people started leaving so i followed some of them. then eric formen from that 70's show was in my dream right after we left the room and he was evil and we were at a campground and he wanted to steal peoples voices so he can like be anyone he wants like transform i guess so he like imitated his dad and stufff and itwas kinda funny and then a school bus came and then i got woken up. ..... does this mean anything????????????????
