This is a dream I had awhile ago, but I still remember the most important part of it. I was looking into this thing that i can only describe as a capsule for that some kind of genie/spirit came out of in this blue myst. While I was staring into the myst the genie said;

(If?)We put a piece of ourselves into the earth, and we can never get it back.

This must refer to how humans can never get the physical body back once they die.

Of course this is contradiction with the theory of a recurrent universe, any thoughts?
