I've been known to carry on whole conversations in my sleep, of which I have no memory.

I do that all the time -- while wide awake. Just ask my wife. ;~))

Me too! Here's a technique that works. Just continually process the last few words she says, discard, and keep recording. Like Tivo or something. When she says "Are you listening?" just play back the last four or five words. Works like a charm.
