You are in a room that is completely dark except for the top of a virtual candle. A meditation teacher's voice instructs you through typical meditation techniques. As you meditate, your world gradually transforms into the fantastical.
It starts with faint colors floating through the mostly black world. You gradually ascend above the candle, eventually breaking the surface of colorful smoke clouds into the black void of space. A lone sun pulsates and supernovas into a Big Bang of particles that swarm around you. You have subtle control of the particles flight path based on where you look.
When the last wave of particles passes you, the Big Crunch happens rapidly in reverse. When the universe finishes collapsing into itself, it is reborn as an abstract sapling. Then you fall back to the candle and return to reality.
