If you’ve been wanting to attempt lucid dreaming ever since you saw “Waking Life,” but haven’t been able to afford one of the exuberantly priced devices, then feast your eyes on this DIY lucid dreaming device. This $30 homebrew lucid dreaming device will deliver you real world cues five hours into your sleep cycle.
Upon receiving the cues, your brain is supposed to distinguish that its in a dream. Once you’ve acquired that thought, you can control your dreams as you wish.
So that means you can beat up the elderly or steal candy from children without fear of social repercussion. That is, of course, if the device actually works adequately. I’m guessing it’ll prolly just wake you up and leave you unable to fall back to sleep.
