My melodramatic fear:<p>The the brain impulses and patterns that comprise your soul are snuffed out during general anesthesia.<p>The new soul that takes rood in your brain will have access to your old memories but is a new set of patterns that only approximate the previous soul.<p>This new soul, of course, will claim to be you in order to preserve itself. Unless primed with the memory of this idea, the new soul won&#x27;t know any better.
