Have you ever experienced the moment when you turn and suddenly you see the world differently. The angle you are looking makes familiar things unfamiliar.
The light changes and you see things you didn’t see before. Are we still in our familiar, everyday world or have we breached a threshold and just for an instant are we somewhere else?
The relativity of simultaneity
According to special relativity each point in the universe can have a different set of events that compose its present instant.(Wikipedia)
And Eternalists hold that time is a dimension of reality on a par with the three spatial dimensions, and hence that all things—past, present, and future—can be said to be just as real as things in the present (Wikipedia)
This concept allows for alternate dimensions and times to exist simultaneously at a given point. In my opinion it is all part of the mystery, the unseen and the unknown and how each person or animal interacts with it.
I have often observed that the world I live in and the world another person lives in are completely different worlds, we DO NOT see the same thing or even hear the same thing. There may a point of correspondence but it is differentiated by the prism we look through, a prism of time, space, experience, choice and attitude. Every person's world is their reality and it is not mine to judge.
There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy.

Image; Herensuge Rock Born - I saw this image in the rock wall at Back Beach one day as I was walking along the beach, when I went back the next day I couldn't find it. For a moment through space and time Herensuge existed for me.
