How many times have you had a dream you wish you could've changed? For me, that happens at least twice a month. Enter the Cerebrex dream mask. The idea is pretty simple.

The mask has built-in LEDs that blink at night to remind your sleeping self that you're in fact dreaming. Supposedly, that "awareness" is what lets you control your dream. Will it work, probably not. And with its $200 starting price, I wouldn't recommend you try one either. – Louis Ramirez
