It is a place beyond existence, between dimensions. You have been stuck here due to being too close to the radius of the space time bomb and as a result, it has erased all of your existence, your past and your present. It is a place where no light reaches, darkness like the end of reality itself, it is a place where consciousness fades in and out and you don't have your body, just a thought. It is empty, no sound, just complete silence.
