The nitrogen gets so thick that you can't see the person you are dancing next to. You look around and it seems like it's just you in the middle of this fog, you can't see the floor, the people, the dj, anybody. Then at the peak of the song playing, they turn on these big vacuums and suck up all the nitrogen. In an instant, you are back in buzz with everyone, it's wild.
