A great book on the topic and rather thorough.

- Keep a dream journal and use it to identify your dream signs. Dream signs are things in your dream that signal that you’re actually dreaming. For instance, did you realize that you were dreaming at the point when elephants started flying? Or was it when you started to walk through fire? Dream signs are important, as most dreamers become lucid when they notice an unusual occurrence in their dream.
- Ask yourself, “Am I dreaming?” when awake, and you’ll ask the same question when you’re asleep. Research has shown that it helps to develop a critical-reflective attitude, which in turn prepares you to become lucid in your dreams. When your dreams seem too real, use critical state testing. See if you can notice whether the content of a book is the same, the first and second time you open it.
- There are two different types of lucid dreams: dream-initiated lucid dreams (DILDs) and wake-initiated lucid dreams (WILDs). In DILDs, lucidity is achieved after losing consciousness when you fall asleep. In WILDs, lucidity is achieved when you keep your mind active while you are falling asleep – that is, you fall asleep without losing consciousness.
- There are a number of ways you can induce WILDs, such as through hypnagogic imagery and focusing on your breath, your heartbeat or yourself. The most popular way is through hypnagogic imagery. Hypnagogic imagery are what you see in your mind’s eye during this transition. They typically manifest in light flashes or patterns which gradually develop into faces and shapes, and then come together to form the scene of a dream. Focus your attention on the images that surface in your mind’s eye. Observe in a neutral way how the images unfold; don’t force them to take shape into anything or anyone specific.
- To keep from waking up too early, you need to engage in some kind of dream activity as soon as you feel the dream starting to disintegrate. You can perhaps touch an object, look at your hands or even just turn around in the dream, for example. If you stay active in your dream, you are less likely to wake up. You might also start to lose lucidity and enter an inactive, unconscious sleep. To prevent this, try talking to yourself in your lucid dream. For example, you might repeat, “This is a dream,” out loud if necessary. When you want to wake up, you should do the opposite of what you need to do to stay asleep. That is, you must withdraw as much focus and participation from your lucid dream as you can.
- Lucid dreaming can be used to improve psychological health by integrating imbalanced personalities. In dreams these can manifest as fears or monsters. Rather than resisting these symbols or running away from them, try instead to embrace their presence. You’ll find that they’ll become less threatening, and as a result, your waking life will achieve better balance too. Nightmares are created by fear. When you face your fears while dreaming, they’ll disappear.
- You can improve skills from your waking life while you are lucid dreaming. The way you can do this is by practicing mental imagery. Studies have shown that mental imagery and mental rehearsal are techniques that can help enhance performance at work and with leisure activities, such as playing football. The more time you give to these techniques in your dream life, the more likely you are to improve your performance overall in your waking life.
