If "consciousness" is "born" somewhere else when you die, you would still need to explain how "consciousness" is bound to a physical body while you are alive.

Your view implies dualism since you are suggesting that "consciousness" is more than just the physical body. You don't need to be a Cartesian to be a dualist but you do need to be dualist if you believe that consciousness is somehow immaterial in that it can survive the body after death.
