I always have weird dreams but i usually forget them the next day. They usually stem from whatever show i was watching before bed. Which lately happens to be Supernatural and/or Queer as Folk, so you can imagine what dreams those two shows could lead to!
Hmm... like two nights ago i dreamt that i was with a couple of my friends but we where running from someone through an (empty) mall - looked a lot like the one near me. Managed to hide, get found, run some more, then when i turned around in a stairwell (which is odd cuz our mall doesn't have one and everything ELSE was the same) i saw that someone else was running with/behind us and that person and the one chasing us had a show down. They "hulked out" like in the movie, all muscles and bad temper LMAO!
Then i woke up. Don't know what that was about but i had the same thing you did - i was there, running, but then at some point i was also an "onlooker." Very strange.
And another time i dreamt i was having a conversation with my mom that went like this:
Me: Mom, my name is Justin.
Mom: No it isn't, honey.
Me: Yes it is, see? (holds out photo ID)
Mom: That's not real sweetie.
Me: Yes it is. Mom, i'm a guy and my name is Justin!
Mom: No you aren't. (looks at my grandmother) Isn't she just being silly?
Grandma: I suppose.
Mom: See even your grandmother agrees with me - your name is Erin and you are a girl.
Me: No, i'm a guy and my name is Justin. Remember i had it legally changed?
Mom: You where dreaming, honey. Your name is not Justin, it wasn't legally changed.
Me: Oh my God.... (stalks off - to apparently find my boyfriend, who was in the men's room)
Then we had to run from the building, because it was collapsing or something, and we all hopped on a train for no apparent reason.
Like i said, weird.
