Human beings cannot imagine things they have not seen, so follow the above basis. Gods, devils, Cthulhu, demons, and anime characters in human imagination, Ultraman from the tokusatsu drama, creatures from Shanhaijing, God, Nordic mythology, etc. Spread out, such as people and things that are imaginary but cannot be verified. Their world should really exist. It's just that I can't see them in the dimension I am in or parallel world No. 1 (Hypothesis No. 1), But I have seen them in other parallel worlds. Although I am not me, I am me. So the people and things that people can imagine now are just reflections of what they have seen in another parallel world in their minds in the current world. Now a kind of collapse of parallel worlds has occurred, and different worlds have begun to overlap. People have begun to see things that only exist in their imaginations...
