Yeah it can happens with me too, not specifically about multiverses but more about the beauty and the immensity of the sky and space. I always been kind of a daydreamer lmao
Whenever I stare off into space, I think of how the Earth keeps moving and will never go back, and how back there, where the Earth was, was all of us having fun without Flat Memphis/Corporate Boring and companies using George Orwell's 1984 as a bucket list.
This picture (which I just made) also comes into my mind.
