How to control your dreams
A lucid dream is any dream in which one is aware that one is dreaming. The term was coined by the Dutch psychiatrist and writer Frederik (Willem) van Eeden (1860–1932). In a lucid dream, the dreamer may be able to exert some degree of control over their participation within the dream or be able to manipulate their imaginary experiences in the dream environment. Lucid dreams can be realistic and vivid. Lucid dreaming has been researched scientifically, and its existence is well established.
Enthusiasts paint it as a world in which, while you're sleeping, you can do whatever you want, or really, whatever you dream.
It sounds like Hollywood fantasy, but enthusiasts say it's feasible with a little training.
In a Brooklyn, New York "lab" for a start-up called "Remee," founders Steve McGuigan and Duncan Frazer show off what they say is a lucid dream-inducing sleep mask. It costs $95.
Frazer explained the mask automates the things you can train yourself to do, from looking at clocks to counting your fingers and looking at text in your dreams. "This basically automates it for you," he said. "Remee provides that anomaly in your dreams. ... You'll see this abrupt bright flash, and it prompts you to check your lucidity rather than having to in your dream to remember to look at a clock."
Although it's virtually impossible to prove lucid dreaming is real, the fact that they have $700,000 in pre-orders shows there is a community out there with big dreams.
