WILD stands for “Wake-Initiated Lucid Dream”, or “Wake- Initiation of Lucid Dreams” to refer to any technique that involves falling asleep consciously. These techniques are similar to self-hypnosis. Some people believe that WILDs are not actual dreams, but are instead astral projection. Various detailed resources are available under that moniker. For most people, they are far easier to induce in the early morning after waking up or in afternoon naps, as the sleep cycle will continue with an REM period. Once you are experienced with inducing WILDs, you can try to induce them at other times. For WILDs to occur, it is best for your body to be completely relaxed. When you go back to bed, lie down comfortably. Now tense and relax your body, starting from your shoulders and working downwards, then back up to the face. This (or similar relaxation, meditation, or trance techniques) should make your body feel slightly heavy and relaxed. There are many different ways to induce WILDs, but they all involve doing something to keep the mind awake as the body falls asleep. A few techniques are detailed below. If you pay attention to your physical body while using these techniques, then you will likely enter sleep paralysis (which usually happens after you're already asleep) without losing conscious awareness of your body. You will get a tingling and buzzing sensation (this might be unpleasant). These sensations might be so strong that you feel that you will die (e.g., you might feel a choking sensation), but don't worry, this is perfectly safe! Sometimes you can simply wait until you fall asleep straight into a lucid dream. However, if you don't fall asleep, and you become completely paralysed (with the exception of your eyes), don't try to move. Imagine your dream hand (or spirit hand if you prefer) going up and leaving your physical hand behind. Now you should have two separate bodies, a dream one and a real one. Control your dream body only — if you control your real one, you will wake up. Now you can try to roll out of bed into your dream world (alternatively, you can get up and walk through a mirror, or sink into your bed).
