WHAT DO YOU SEE AND HEAR? What you see will depend on your own brain's reaction to the sensory stimuli. The possibilities are anything from abstract designs to realistic scenes. Your brain uses the stimuli to create imagery in much the same way it uses your memory and psychological systems to create imagery during dreaming. You can now program your own sessions to get the type of stimuli you respond best to. The sounds you will hear are modulations of tones that enhance the effects of the light patterns. These are also self-programmable.
