Imagine you are locked in an unlimitedly large room forever
and you’re the only one there ever was.

Yet in this room you can do anything you want
including clone yourself and experience the room
from multiple points of view,
encountering yourself from different angles
and interact with yourself.

This room contains invisible structures which empower you
to model any conditions with which
you will experience everything the room,
such as the ability to manifest any bodily form
and any mental structure through the balancing of conditions
in a computer-like interface that appears when you close your eyes.

What crazy levels of novelty would you manifest to fend off boredom,
and how would you maintain the balance of your creations?

Welcome to the universe.
