Just some odd dreams?

Hi there, I keep having these dreams in which I meet a person, and the same person keeps saying to me "I'm your Sister", But in real life I don't have a sister. It's always the same person.

Also, while I'm here, I keep having another recurring dream in which I'm in a factory that makes universes, and it's all very detailed(the processes they go through).

But the one about my sister is just puzzling.

Any ideas?
