It is a reference to the TV series Lost. People are trapped on an island where mysterious things happen. These numbers appear often in that show. One place the numbers appear is on a metal hatch they find in the jungle. The hatch leads to an underground complex. The people consider hiding from their enemies in there. So your picture and title are remind me of the Lost hatch.
