One of the things I actually wonder about is when people describe this existence as a form of holographic reality, which many seem to see it as, your whole life is often described as just a movie projected on a screen with you being the projector (who can jump into the movie).
That way, nothing you could do would really matter, except as a learning-project for yourself. The only thing about this is the seeming objective existence of other beings who you can interact with and affect in different ways. At least here it seems real, but who knows, it might be like with a dream where you seem to be able to borrow some of someone's soul-essence so you can interact with anyone, or seems like we all have some of our soul-essence available to anyone who wants to interact with it.
That way it would seem real, but it wouldn't be real, like a short dream. You can also do extreme things to others, like kill them, in dreams but it's not real (or I don't believe the ones you dream about experience the same at the same time). Sometimes it can seem like you're really interacting with someone on some kind of non-physical plane, but it might as well be just you in a world of your own, where you can create anything you can imagine. So it's like we're all just dreaming different dreams. I can't say for sure it's not really like that.
