Smart headband claims to be able to induce lucid dreams

There are never enough hours in a day, our over-connected culture often says. But connected devices worn nightly do not aim to lengthen our days with more tasks; instead, they help us optimize the hours we do sleep, and thus improve the quality of our working and playing hours. For some, better sleep is achieved through lucid dreaming, or being aware that you are dreaming, an experience said to lower stress and improve performance at tasks you “practice” in dreams.
