When a mortal is alive the psyche produces alpha and genus Beta wave . Between both , beta waves are rife . As a person receive drowsy , the alpha wave becomes preponderating .
Stage one is the light form of sleep and lasts between 1 minute and 5 minutes . During this stage , the alpha undulation drops to less than 50 percent of the total brain wafture . The research worker in this stagecoach observe ripple of slower theta waves(2 ) .
Hypnagogia occurs in the period when the alpha waves are decreasing but have not reached the first stage . This is the transition stage .
