Multiversophobia is the fear of the multiverse.
The Multiverse is what you live in. The theory is that we live in a universe and that the universe has an end and there are many other universes very similar to ours but some might have a small difference like you shaved last night or a major difference like you have wings. the multiverse is the theory of infinite realities of ours and no one knows what the base universe is. or do we?
