How can I comprehend existence and non existence?

I need to comprehend it, I've tried roleplaying a conversation between the universe and non existence but I always stump myself with questions that are too big and vast for me to theorise. I need to learn how to see the universe from the perspective of no perspective on a universal level rather than my human way of seeing just the world if you get what I mean.

If anyone out there has been able to understand what is and what has been then please let me know how you managed to see it from the view point of nothing.

I'm sorry if this is confusing, or if you feel I am in error but I am very muddled at the moment and need to figure this out so I can sleep sometime in the near future.
