ConCeption (2011)

When a girl complains to her friends that her father will not let her attend a science fiction convention; they decide it is time for an inception. While reading his bible, the father falls asleep and suddenly finds himself in standing in line at a convention. He dismisses them as "loser weirdos" but overhears a conversation from others in the queue that makes them sound intelligent. But he must go deeper. He wakes again in the second level, a surreal panel. The agents burst in and tell him he is trapped in a dream and must escape with them. People in the dream are becoming aware of them and beginning to fight back. An exciting shoot out still disappoints the father, so he is taken to the third level. Dressed strangely, he is at the dance where he sees his daughter having a great time and being complimented for her costuming. He realizes that this is what makes her happy. The agents kick him back to the second level where he joins in the shoot-out with much glee. They kick him up to the top level, a surreal scene where three people try to blow out a candle. The father walks in and says you need a badge to put it out. Later, in the real world we see him talking on the phone with his daughter telling her he will drive her to the convention. He then picks up the book he was reading: a Dungeons and Dragons handbook.
