A WILD is called "Wake Initiated Lucid Dream." Its a method in which you attempt to transition into a lucid dream from a waking state. Basically, being awake and going straight into the dream as you go to sleep.

WILDs rarely work unless accompanied by a WBTB. WBTB stands for Wake-Back To Bed. This is getting not quite a full nights sleep, utilizing your motor functions for 15 minutes to an hour (reading, walking etc.) and then going back to bed.

The trick is causing a sort of REM rebound, and that you'll end up with an extra long, extra intense REM period. As well, since your body was just sleeping, it makes it easier to get back to sleep. With this, the WILD becomes easier and you'll transition straight into a deep REM sleep, with incredibly vivid dreams.

Attempt a WBTB before your WILD, and you'll likely see better results.
