I once read this book called “The Book of Atem” which talks about the existence of “memetic entities”. In essence, the concept explains that memetic entities are thoughtforms that live in multiple people’s minds. For example, Superman is a comic book character that has been interpreted in film, television, comics, mentioned in songs, and so forth. Superman has a backstory and heavy influence on pop culture and if you were to die tomorrow, Superman would continue to live on in the minds of millions of people.
