I'm starting this topic because I'm curious as to others' experience in using these to either help them fall asleep or to get better quality sleep at night. In the past, I've found guided meditation tracks very helpful in falling asleep. I'm new to NLP/Hypnosis however. Last night I tried the hypnosis CD that comes with the "I can make you sleep" book. This was the second time I've used it, and my intention was to listen to it, take it off and go to sleep afterward but I kept the headband on just in case. I woke up to the track still looping 4 hours later.
What I found was that while I typically lapse into REM within a half hour (and sometimes much shorter) of going to sleep last night I stayed in light sleep for a full two hours before transitioning into any other phases. So, it looks like listening to the track on loop was actually detrimntal as the continuous dialogue seemed to block me from progressing forward into other phases of sleep. Of course, this was just one night. Many nights of data often change the overall picture somewhat.
So, what are your experiences/ experiments with how listening to these things while sleeping have impacted your sleep?
