I'm not sure of the details, but I was somehow involved in making a TV show or movie about the "ancient Japanese tradition" of fighting the dead. People would go into a tomb/crypt type place
and fight the "dead" person in there, who was really alive. If the dead person won, the loser had to stay in the tomb and be dead.
I thought the whole thing was sort of bizzare, and mentioned to a co-worker that if they were fighting dead people, shouldn't the people actually be dead? My idea caught on, and the fights got a lot scarier, with people killing each other in the dark.
Also in this dream, someone mentioned that melted cheese was on sale at the deli of the store I work at.
