The way this discussion is going, we're going to get an outbreak of amateur 
seismologists connecting themselves up to electroencephalographs, so that they 
can correlate the interruption of sleep witn the seismic record.  :)

It seemed we always would wake up and then the shaking would begin.  I don't recall any such feeling for awake time quakes but while sleeping there seemed to be something early enough to feel awake first.  It wasn't a special feeling like here comes a quake but clearly awake enough to be aware of waking first.  Has anyone else experienced something like that?  I've always attibuted it to the P wave.  It would have been fun to have a seismograph back then to correlate timing.
