Hm. In quantum physics, the pieces that make up our reality can exist simultaneously meters apart, in negative and positive states. Can move as waves, yet when observed at any particular moment in time, perhaps act as a particle instead. The way we understand physical, observable matter is often at odds with what we know about what it's constructed of. If the atoms, the molecules, that make up your body can be in multiple phases, then why can you not? The accident, that you correctly surmised, well. I've become the research that my father dedicated his life to, that he lost his life to. So yes. Odd results.
You seem like a fairly well adjusted... kid. It is good to be aware that not everyone will have your best interest at heart, when they take you in. But as safe being alone can keep you, it can also drive you mad. Take it from an absolute hypocrite in the matter.
