Pfft Solipsism is old news.

Quantum solipsism is where it's at.

Not asking if everyone around you is dreaming but if your consciousness is what ties you to your reality and the multiverse theory is true.

Lets say there are infinite universes based on all possible combinations of quantum particles from one moment to the next right?

So if you get hit by a bus walking across the street and die there is also a universe where small changes lead to you noticing that bus and not getting hit.

Your mind can only observe in the universe where it doesn't cease to exist. Hell it only came to exist in the universes where it could observe.

So you don't create the world around you, you are its observer and can't stop. Other observers aren't tied to you though, they can stop observing but you can't.

This would mean that each person is locked into their own little bubble where you coexist with some observers in some multiverses but we are all destined to move on slowly becoming more and more isolated as we are forced to remain in the universes where we can exist.
