Dream stage enhancement uses a headband with EEG-EOG sensors, onboard processors, memory, coarse and fine time REM waveform detection modules, LEDs and an audio playback unit. After normalization to the user's EEG waveforms, the user's EEG-EOG signals are processed, REM and NREM stages detected and light, sound or AV stimuli are presented to the user based upon user-supplied light-sound-AV stimuli commands. To provide a reality check control (“RCC”), the head unit has a user actuatable RC interface whereby during sleep, RC stimuli are presented when the user depresses the RCC control which plays back the user supplied stimulus. In a “learning mode,” the user selects “Recall” or “No Recall” (“NR”) after the sleep period. If NR, then the system changes the color of light stimuli, light intensity, flash, audio sound type, audio intensity, and AV. If “Recall” the user supplied stimuli commands are carried out.
