WASHINGTON: A new headband that can measure brain waves and eye movement activity to allow a sleeping person to take control of their dreams has been developed.
The headband works by determining when a person enters REM sleep — a stage of sleep characterized by rapid eye movement where dreams are more likely to occur — by measuring brain waves and eye movement activity. Then, it emits a series of lights that will not wake up the user, but instead allow them to realize they are dreaming.
