A new headband has been launched that promises to help dreamers realize that they are dreaming. According to technology developers, the headband is designed to measure brain waves and eye movement activity to determine when a person enters REM sleep. Once this state has been identified, the headband then emits light to indicate that the sleeper is dreaming.
This new development has had mixed reviews throughout the scientific community. For more information on the device, click the link below:
