I know one or two people who are able to dream lucidly, often experiencing Out of Body Experiences (OOBEs), more or less whenever they want to. For most of us, though, lucid dreams are something that we can only imagine. A couple of guys from Brooklyn are about to change all that, though, having successfully raised over half a million dollars via the Kickstarter crowd funding platform to create the Remee Mask. Here they explain what it is:
What is Remee?

In essence, Remee is a specialized sleep mask. You put it on before you go to bed and with practice and determination, it should help increase the number of lucid dreams you have.

So how does it work?

Sleep stages are divided into two main categories: non-REM sleep and REM (Rapid Eye Movement) sleep, where dreams typically occur. Over the course of the night a sleeper will cycle through the five stages of sleep a number of times with the REM stages lasting longer and longer towards morning.

In default mode, Remee targets these long chunks of REM sleep towards the end of the sleep period. Before bed, turn Remee on, fine tune the brightness of the lights (if needed) and then go to sleep. Remee will wait for an initial long delay, usually 4-5 hours, until you’re in the heart of the heavy REM stages, before initializing light patterns. After the initial long delay Remee will display light patterns for 15-20 seconds with a second shorter delay, default at 15 minutes, between each signal. During non-REM sleep the lights are unlikely to effect you, but if you’re in REM sleep the lights will bleed into your dreams, presenting a perfect chance to become lucid.

Why six lights and why red?

We spent a lot of time making sure that Remee’s lights were configured in such a way that it would work well for all face shapes and head sizes. Six lights creates a much larger effective signal area so that even if the mask shifts during sleep you’ll still most likely have at least a few lights over your eyes. Even cooler, by having six lights we make it possible to create much more unique signals that can strobe, sweep and blink in ways that are not only recognizable, but that stimulate your visual field in a more tangible way. In addition, red light penetrates skin much more readily than other wavelengths. Remember when you were a kid and you put a flashlight in your mouth to make your cheeks glow red? That happens because red light is able to pass through your skin, and in the case of Remee, your eyelids, much more easily. On a side note, red LEDs also use much less power than other colors so we were able to keep you from strapping a 9v battery to your head.

Customizable, you say?

You bet. You’ll be able to edit the standard full night sleep long delay and short delay, as well as setting both the short and long delay for nap mode. Nap mode lets you trigger signals after a delay as short as 15 minutes – perfect for a quick lucid siesta. This is also great for the Wake-Back-to-Bed technique, which veteran oneironauts can attest is one of the best methods for lucid dreaming. In addition to setting Remee’s timing, you’ll be able to select from a variety of unique signal pattern sand also modify the brightness to suit your paper thin or ogre thick eyelids.
