I've recently been reading about this and I find it quite interesting, I have ADHD and have been trying to attain lucidity by the methods posted on here, and I cant. I am not sure if this is my fault and that im not trying hard enough or if i have adhd. I take medicine for adhd. At night i basicly take sleeping pills that make me very sleepy, so it might be that im in too much of a deep sleep to realize that im dreaming, but i have a tleast 1 dream every night. im not sure also because everybody here is able to do reality checks in non lucid dreams to try and become lucid, but for me non lucids are just not being able to control myself at all, kinda like a movie.
