Observation
There’s a theory that when we die, we are reborn.
Reborn, however, in a fork of our last reality.
In a reality that shares a distant history, but that has been further crafted with a different random walk of time.
Some relics exist in both realities because of that shared history, though some because of a shared inevitability.
And Déjà vu is our pattern recognition transcending our current life’s experiences.
While dreams are the hallucinations of our past realities melting with our current one.
