There's actually a theory that your dreams are your soul/spirit/essence actually living a life in another dimension. Which is allegedly why, if you die in your dreams you die "in real life".
I have died in dreams plenty of times, I am still here. Unless this is a dream of course. In which case I may not be here, but, rather, just an analogue of comma overuse.....
I've always wondered how one knows if they died in a dream.
I mean, how does one know they weren't saved somehow, after everything "went black"?
I suppose I don't. It seems to me that what I can comprehend in the dreamtime is more than what I can comprehend day to day.
Think what you should have said as there may be infinite amount of universes. Dream is just a label we put on a brain state there is no reason to believe it’s anything more than that
