I thought there was a little more to it than an increase in BPM... according to this there should be an "increase in the chaotisity (decrease in D2 degree of freedom)":

Any way that you could provide sleep logs?
Hi, sorry, im only an 'ideas' guy. The reason my CanWild is successful is because i set alarms 20 mins apart after 6 hours sleep so the chance of my alarm waking me during a dream is over 90%. I only have google researched knowledge about the increase in heartbeat during REM. If you could continue your work with the iWatch in mind then you could create one of the best every DEILD devices in the World. Sorry that I cant contribute more to this :-/
