WILD is considered the "holy grail" of lucid dreaming techniques. Based on what I've heard and experienced, it's also the most difficult. It's supposed to give you much more vivid, detailed, lucid dreams, but I can't attest to that personally because I've never been able to do it.

I did have lucid dreams occasionally in the past especially during nightmares. But during those nightmares I would realise I was dreaming and force myself to wake up
Sounds a lot like me. My first lucid was a nightmare when I was fairly young, and after I decided that it must be a dream, I woke myself up on purpose to escape the monster that was chasing me.
