You’re an alien. Last you remember, you were flying in your ship away from your exploded planet. You had been traveling forever and never considering you went through a white hole (The opposite of a black hole. Serves like a portal through time and also place).

Your ship went haywire after you entered an unexpected solar system. You steered for a planet, in fear of falling into nothingness.

When you awoke you were on a table in front of some whacko in a lab coat. You were in a lab.
