The 90 Minute Dream Cycle

One dream cycle is usually 90 minutes, where delta waves slowly increase frequency to morph into theta waves, which is the REM state of dreams. The awakening cycle in the morning, when the transition takes place from theta to alpha and finally beta (when we hit the snooze button!)

This precious morning time can be made highly productive as it is ripe with new ideas and insights related to the events of the day before and the forthcoming day.
