Hmmm, well, I might not be dead for real. Since I died in a simulation. Though, the chance to end up brain dead is rather high when you believe it happened, or experience it in a convincing way. Since I haven't woken up from it, who knows which is which? I woke up here instead, the same as before. I suppose in a way it's like an unknown state. The truth won't be known until observed. For the moment both possibilities exist at the same time.

Other potentials are that right now I might simply be a digital copy of myself. It's a bit strange, isn't it? And in that case whatever the state of my original body doesn't matter.

But don't worry... it wasn't sudden, it was very well planned.
