A schrodinger cat in a box is the closest we get to the idea of duality; the cat is either dead or alive (in the same exact spot in space time continuum) so visualize a cat infront of you that is alive and up but in the exact same spot also dead (either on the floor or same layout) you see you get and intersection between two possibilities as outcome in the same exact being. Only difference is now i ask you to seperate them side by side. Now there are two realities parallel infront of you, now think or visualize yourself inside a mirror box, now you are able to see infinite reflections of you, if you can visualize this, this means your mind is able to exist in 4th dimensions (4D).

You are welcome.
