There are ways to psychologically train yourself to recognize when you are dreaming. But for those of us who are less mentally trained, of the has shared a way to that will help you trigger a lucid dream whenever you want.

The build consists of a pair of safety goggles with some red LEDs that shine light on your eyes. The lights are connected to an microcontroller and an that's been programmed to start blinking the lights every 10 minutes after a two-hour delay.

The idea is that the system will start blinking the lights once you've gone into where dream activity is more likely. The lights will, theoretically, catch your attention without fully wake you up, and then you will know that you're dreaming.

In a lucid dream, you supposedly can take full control of your dream world. So you can climb a vertical hill, get attacked by a waitress holding two trays who starts spinning like a toy top of doom (I've had some weird dreams...), turn the world on its head like Ellen Page did in the movie , or act out whatever fantasies you have.
