In the world of your dreams, you can build an entire world, an entire universe, an entire society governed by your every whim. While lucid dreaming you are a god in your own mind, free to create or destroy at will. You can train yourself to recognize when you are dreaming, but sometimes a little technological help can speed you towards the path of becoming an old testament god. [Will] over at revolt lab built a set of lucid dreaming goggles so he could take control of his own dreams.
To induce a lucid dream, [Will] took a pair of safety goggles and attached red LEDs to shine into his closed eyes. A simple circuit was constructed out of an ATtiny85 that blinks the LEDs two hours after being turned on. The idea is these LEDs will be noticed by the user during REM sleep and they will realize they’re still sleeping. After that, it’s basically Inception.
It is possible to induce lucid dreaming through psychological and not technological hacks; just asking yourself, ‘am I dreaming’ throughout the day may be enough to make a holodeck in your mind while you’re sleeping. You can check out a video of [Will] wearing his goggles after the break.
