Transmigration of the soul

Today Ed Ockham describes a waking thought that reminded me of a similar experience of my own a few years ago.  I had been reading Colin McGinn's The Character of Mind.  At one point he describes mind as a 'centre of consciousness' or some such; or perhaps I had been unduly influenced by talk of the demonic neuroscientists that philosophers of mind like to think about.  Anyway, on waking I had the thought:  What if, while I was deeply and dreamlessly asleep that night, God had taken away my soul and given me another?  I distinctly remember a ghastly 'falling through the floor' sensation.  How was I to get my proper soul back?  And then the thought occurred that this was precisely what must happen every night, and I stopped falling.
