Is lucid dreaming actually a thing or do people just make it up?

Ever since I was like 13 I used to watch videos on youtube on how to lucid dream but not a single video worked, which really dissappointed little me. I thought people just used to lie about it for views and gave up, and yesterday I came across this sub where people share how they do it. I tried one of them but didn't work.

Is it possible that lucid dreaming just doesn't work for certain people or am I doing something wrong. I really wanna know what lucid dreaming feels like. It sounds so interesting and cool
