the idea of dreams being memories of alternate realities is a fun one that i'm gonna have to marinate on for a bit. i dig the concept of it for sure, but i very much doubt there's any scientific or physical way to prove it (yet).
either way...definitely one of the more interesting questions i've seen posted here. thanks for getting my gears turning this afternoon!
Yeah, right now I don't think there is anyway to prove it. In the future, hopefully we discover something. Thanks for reading :)
