There was a woman whose husband is a clown. She was cheating on him with Matt Damon, who in this dream was a soldier in addition to an actor. I don’t know whether or not her infidelity was related to her husband being a clown. Anyway, she and Matt Damon were inside a movie theater together when her clown husband died inside a candy machine in the lobby.
The whole feel of the above situation was like a suspense movie… Think psychological thriller.
