Until now, that meant lots of hard work practicing some form of mind control with little guarantee of success. Mind machines come in a number of forms and flavors. The most well-known and effective measure the brain's electrical activity and then pulse lights and sounds to control that activity. Such devices, through flickering lights and precisely controlled rhythmic tones, stimulate and synchronize the hemispheres of the brain while entraining the brain wave frequencies into desirable states of consciousness. If you select a session with a target frequency in the low alpha or theta range, you should feel a change in awareness within a few minutes.
Many people report a floating feeling.
Your attention may start to wander as your thoughts become less linear and logical. Perhaps you may find yourself in a lucid dream complete with sights, sounds and feelings. Some people, auditory types, often hear words in the pulsed sounds. This indicates theta activity and heightened creativity. Because your sense of time changes during the session, it may seem as if you have slept.
