You don't need to lie to yourself to get it right. You really can become lucid based off of your belief in yourself. Lucid dreaming is so easy. Think about it like this if you need help thinking that: You have many dreams every night and it only takes 1 SINGLE THOUGHT to make you lucid. Really, it's nowhere near as hard as most oneironauts seem to make it. Also, Lucid Dreaming can work in the very same way that people use natural alarm clocks. I've done it before and I know others have too: Before you go to sleep at night you set an intention to wake up at a very specific time. Then you go to sleep and before you know it you've awoken at the exact time you wanted to without any alarm clocks.
I once did an experiment(last summer I think) where for 3 days, right before bed I would set an extremely strong intention to become lucid in every single dream of the night. I became lucid at least twice every one of those nights. And that was when I was a beginning lucid dreamer. Destroy those bad schemas that say you can't do it. I mean really, it's your dreams, what's so hard about simply realizing that you are dreaming? Many make it into an extensive effort when it doesn't need to be! I know I'm probably going to get some hate for this post haha.
