Maybe there is a world that mirror's our own but in that world our technology is advance or maybe magic, monsters, and aliens coexist alongside us that would be amazing if that is case.
"There are two things you should remember when dealing with parallel universe. One, they're not parallel, and two, they're not really universe." Douglas Adams
I'm sure we all have our own differences when it comes to conversations like these, but I'll say this: if I had the ability to see the beyond, would it be interesting, scary, outrageous, all of the words I can think of, what would I think of first is what I'll always end up asking myself, and it'll always have me curious on the world that mirrors our own and the creatures/entities most of us are incapable of seeing. We can only be curious in either case, right?. Bon voyage.
