Thread: What could this possibly mean?

(I was the camera in this dream so I couldn’t react to anything). 3 people were sitting around the colosseum in the town on one part of the dream island and there was an earthquake.

A hole opened in the colosseum and people started falling in from the town. The 3 people ran across the side trying to get out but 1 fell in. The other 2 escaped. For some reason these people became immortal and millions of years later, after wandering the Earth for millions of years, came back to this very spot and started wandering around.

They had lost all memory of this event and started seeing things that brought there memory back.
There memory had not fully come back but they went to the colosseum and punched the ground and it broke. They climbed down and then saw there friend who had been buried down here for millions of years.

At once all of there memories returned and suddenly strange creatures appeared. The were fully black and had no eyes and could speak telepathically. They had evolved from the townsfolk that had been buried down there. The dream ended there.
