I hate to burst your bubble, but every technique there has some kind of learning curve - especially WILD. There is no "instant lucid dreaming method" that works immediately and consistently, and anyone who tells you otherwise is a liar. Think about it, you're essentially retraining and rewiring the way your brain perceives your surroundings - that doesn't happen overnight. The brain is a muscle, and muscles need to be strengthened before they can be used effectively.

Think of lucid dreaming as a marathon. You don't wake up one morning having never run in your life and decide that you're going to complete a marathon. Long distance running like that requires training and consistent practice. Trying to use a technique to skip all the training is like deciding your going to race with roller skates on to make it easier, because there's "no learning curve". Sure, you might be able to have rare, random successes - like if the entire 26.2 miles is entirely downhill, and there's no crazy hairpin turns to throw you off-course. But typically, you're going to still fail with the roller skates on, because your body hasn't had that training to be used to the physical exertion skating still requires of you.

It's not uncommon to want an instant method for lucidity, but searching for one is often more detrimental to your practice than just biting the bullet and putting in the hard work for it.
