A brainwave is a pattern of electrical activity in the brain that can be measured by an electroencephalography (EEG) machine. Theta waves in brainwave activity can be observed when one is in a drowsy state – the state that you are in upon waking up or right before going to bed. This is a highly desirable state that has the potential to unlock altered states such as creativity, peak performance, and heightened intuition.
With standard meditation, it can take years to get to this place and stay in it for long periods of time. However, brainwave entrainment technology can synchronize your brain to these states much faster.
