Mysteries of my subconscious

I was in an office building where there was a huge party going on at the time, and then i kicked out and I had this thing that allowed me to kinda float through the air, if I pushed the button in the air. So, I was forced away from the party and I was extremely far away at that time. I was with a tv show character, Barney from How I met your Mother, and we were on a mission to get back to the party because there was some sort of scandal going on there. We were extremely far away, and we saw a building that was a lot quieter than it, but we decided to check it out, just in case. It appeared to be an abandoned building with maybe CIA agents working in it, only on one office near the top floor. Me and Barney evacuated it quickly. We began to walk again looking for it, and we though we saw the lights coming from the direction it was. I used the thing to float to get over there at high speeds, and I realized it was there. I went back for Barney and he was in an outdoor mall at the time. I got him and we prepared to use the mechanism to fly over there, as soon as I woke up.

This was a pretty cool dream, it's just extremely unfortunate that was an entire beginning to this dream that I don't really remember besides the ending. Also, there was more to the beginning of this I don't remember very well.
