Like PyroGuy305 said, dream journals and reality checks are vital starting points for any novice lucid dreamer. It takes a lot of dedication to wake up every morning and write down 1 or 2 dreams (or 5 dreams when you get better) and do reality checks all day every day, but all this effort pays off (at least for me and nearly everyone else I've talked to) because you're conditioning your brain to constantly be thinking about dreams and the possibility you might be dreaming.

Even if you're not really "yourself" in your dreams, if your dream self remembers to do a reality check, and you attempt to perform it and realize you can't perfom your reality check because you feel like you don't even have a body, that alone might be enough to force you to realize that you're dreaming.

So just stay motivated and keep working towards the goal of lucid dreaming and you'll be rewarded, eventually.
