How do you convince someone thats ignorant that lucid dreaming is real. My mom's boyfriend is being a jackass, and thinks im taking medication or something. I took a little melatonin, thats all. He believes that dreaming is something you can't control. Is there a simple way to explain to him without making either of us seem like a jackass. Would be helpful.

PS sorry if i posted this in the wrong area, couldn't find a right one.
