Sleep, Dreams and Lucid Dreaming

From the guide

Every night you surrender. Your muscles go slack, the outside world fades, and for a few hours your brain stages vivid worlds you will mostly forget by breakfast. Then you wake, and call it nothing.

Sleep is not nothing. It is one of the most active and important things your brain does. During sleep, memories are sorted and strengthened, emotional experiences are processed, and the brain clears away metabolic waste. Dreams, once dismissed as random noise, appear to play a part in some of this work.

And sometimes, in the middle of a dream, something unusual happens: you realise you are dreaming. This is lucid dreaming, a state that scientists confirmed in the laboratory in the 1970s and that Tibetan Buddhist practitioners have cultivated as a spiritual path for centuries.

This guide covers what science knows about sleep and dreaming, the lucid dreaming techniques that have actual evidence behind them, practical habits for better sleep, and how the tradition of dream yoga treats the night as an opportunity for awakening. As always, every claim is labelled so you can tell established findings from emerging research and contemplative teaching.
