Most techniques require that you wake up after about 5 hours of sleep so that your next sleep phase is a REM (Rapid Eye Movement) phase. In this phase, you dream particularly intensively. In the waking phase before this, you should, e.g., activate your mind or set the intention to lucid dream, depending on the technique.
Besides the fun factor, you can train your skills, fight nightmares and access your subconscious mind.
Contrary to some myths, lucid dreaming is not dangerous. If you have healthy sleep, you can try lucid dreaming without hesitation. You can read more about the topic here (link to myths).
The most critical points are to keep a dream journal, do reality checks, tune in before going to sleep and try the different techniques. With WorldWithin, you can access all of this in one place. Learn more about how to learn lucid dreaming here (link).
In a lucid dream, the dreamer gains awareness that they are dreaming. Research has shown that lucid dreamers have a larger brain area that allows them to think about their own thoughts and is responsible for metacognition.
