Horowitz and his colleagues at the MIT Media Lab have developed a relatively simple device called Dormio to interface with this unique stage of sleep. Their hypothesis is that this liminal period between wakefulness and sleep is a fount of creativity that is usually lost in the ocean of sleep. The thinking is that if you’re able to descend into that stage of sleep and return to consciousness without descending deeper into sleep, you will benefit from the intensely associative thinking that characterizes the strange microdreams experienced during the transition to sleep.
So far Horowitz has tested the device on 15 subjects and found that it is able to reliably maximize the amount of time users spend suspended between wakefulness and sleep, as well as shape the content of the microdreams they experience. In other words, these MIT researchers have developed a low cost device that allows users to interface with sleep.
