I love sleeping and its one of the most wonderful works for me apart from day to day curriculam. I am so much obssessed with sleeping that I have decided to do lots of research onto it. I have experienced that people do not sleep instantly after going to bed. It takes time for them to go to sleep. So, there must be some stages for people to fall asleep. I wish to know about different sleep stages, so that I could continue with my research on Sleep Stages.
