A handy guide to lucid dreaming, with additional tips from Richard Feynman

Anyone who's had one will tell you: lucid dreams are ridiculously, comically, and sometimes obscenely fun — but they're also notoriously difficult to experience. In their latest video, the folks at AsapSCIENCE serve up a series of quick, scientifically informed tips on how to experience nighttime reveries on your… »10/11/12 12:30pm10/11/12 12:30pm

Neuroscientists successfully control the dreams of rats. Could humans be next?

Researchers working at MIT have successfully manipulated the content of a rat's dream by replaying an audio cue that was associated with the previous day's events, namely running through a maze (what else). The breakthrough furthers our understanding of how memory gets consolidated during sleep — but it also holds… »9/03/12 11:00am9/03/12 11:00am

Why does falling asleep sometimes feel like falling down?

We've covered sleep twitches, the unconscious twitches that people make while they're asleep. They're the result of the unconscious and conscious brain both being online at the same time.
