Holy freaking ****, I have just started to train to become a lucid dreamer I am not even ****ing kidding. This thing might come in handy.
That's super cool O: I've only had like one lucid dream in my whole life, but they always fascinate me
Except you will not automatically have one just because you put that thing on. It still requires a lot of work. For some people it comes natural, but for a lot of people it takes training, even if you have one of those things. Don't expect immediate lucid dreams when you use it, it'll probably boost your chances though.
