How can you cause a lucid dream?

To cause a lucid dream, remember ordinary dreams, keep a dream journal, imagine yourself re-entering past remembered dreams, and then seek peculiarities that differ from waking life. Form awareness habits during waking hours that carry over into your dreams.

1. Try to remember dreams

   Before falling asleep, tell yourself repeatedly that you're going to remember your dreams. Make a habit of this until you start remembering dreams. Upon waking, immediately try to recall your dreams.

2. Document dreams

   Make a habit of writing down what you remember from dreams. Do this immediately upon waking so you don't forget details.

3. Attempt to revisit a dream

   After waking from a dream, picture yourself falling back into the same dream while telling yourself to remember that you're dreaming. Imagine that while you're in the dream, you're actively looking for abnormal phenomenon that wouldn't happen in waking life. Ideally, this questioning may carry on into the next dream.

4. Focus on your waking life

   As you go through your day, take time to recognize your surroundings. Sense things, and acknowledge them. Eventually, this sense of awareness carries into dreams, helping you to realize when something is different. Ask yourself if you're dreaming during the day so that it becomes habit to ask yourself if you're dreaming during sleep. The realization that you're in a dream causes lucidity.

5. Remain lucid

   It's normal to become excited upon realization of lucidity. Try your best to remain calm in order to remain in a lucid state.
