I have a theory which goes this way:
MindVerse Theory
It states that "Each individual live in his/her own Universe, that is created by him/her only"
For example-
There are two people A & B;
A lives in his own Verse -: A-Verse
B lives in his own Verse -: B-Verse
A and B meet, they come face to face,
The A-Verse
The B that is existing in this Verse is the B from A-Verse.
This B is being projected by A itself onto his A-Verse.
The B-Verse
The A that is existing in this Verse is the A from B-Verse.
This A is being projected by B itself onto his B-Verse.
In a nutshell, Our surrounding are just projections of our own "Consciousness".
We make our own Universe.
