Have you ever wake up and wondered about having a very unusual dream, wherein you are in an unfamiliar place and unfamiliar people, it could be the version of you but in different world. There could be a parallel world in our vast universe. Remember having dejavu's those moments could be the same timeline with the other universe. There could be many versions of us. Just a single change in our actions could lead to a different future. I believe in parallel universe, what about you?
