Your dreams and imagination evolved as a view into another universe. As with the current beliefs, you cannot decipher technical information – no words in books, no details of how devices work, so even if you can describe things you see from another place, you could not reproduce a working version.
Now how do you convince others that the things your are seeing are really happening without being labeled insane? And how could you use this information to benefit yourself or others? Take a peek into the multiverse to see how other versions of yourself have solved these problems…
I had dreams of omnipotence. Including omniscience - they knew I was dreaming of them. In fact, one of them was particularly aggravated that I was aware of them.
If those universes are real, then they could contact me in this one.
They have not. So those gods aren’t real.
I dunno what this changed.
