The particularly heinous and voodoo twist delivered by tetradotoxin is that this apparently dead person is fully conscious. It is difficult to imagine being pronounced dead in a room full of grieving relatives and you are without the slightest ability to communicate. This is not to mention the pure terror of being buried alive without the ability to render understandable objection. If the victim survives burial or some other horrible fate, the return to the living occurs within a few hours to a few days.
