Is it strange that whenever we dream and if we feel realistic in them we are actually traveling in a parallel world??

That would be amazing, much better then here..... unless when is a nightmare

There's a concept about this in some places. There's a reddit called mallworld or something. I joined the chatroom and it seems sort of fantasy esque whether for izzels, or for fun. Anyway they all apparently dream about the same place, which is the inside of some gigantic shopping mall realm, and they talk about different features and places within they 'find' while dreaming. I haven't looked into the activity in the chatroom (discord) too much, but I offered some kind of ideas about psychology and they really seemed to like it.
