When sleep learning try to do it every other day so that the mind can process the stuff you dealt with during the day.
Periodically during the night you may pay attention to the material you are listening to. It's probably better to start it about 90 after you fall asleep when you enter your first dream cycle. This is usually a short dream cycle of about 10 minutes so.
The court remains out whether sleep learning really works. For some are able to tune out outside noises during their sleep period than others, noisy trucks, trains passing, refridgerator turning on and off. Others take a while and I wouldn't be surprised if those folks have more success with sleap learning.
