Random and unique dream

Hello!

My weird dream happened last night. Here goes:
I was in my friends van with two other buddies, it was dark probably night time and for some reason he was driving on a park sidewalk but very slowly, kind of like he was walking the car; driving at a walking pace. But I am not sure what happens but there is a fence, very high, blocking the sidewalk I get out and hop over it. I follow the sidewalk and their is some sort of portal like thing at the end I jump through and enter a new dream. This dream I was on a couch with the same friends and it looked a party was going on, all I can recall is my friend looking behind a couch and seeing a passed out person on the floor.
This is where it gets weird, I played a lot of team fortress 2 the day before and in my dream I was the medic and I was healing a player but I distinctly remember thinking to myself "This is not a dream, I want to lucid dream" something of that sort. I was doing the mantra "I will remember my dream" a lot before bed. But still I find that a little weird, in a dream saying its not a dream? Has anyone ever had that happen?
