I feel your pain...
You were not in the wrong at all for the first two questions I however do not know the name of the book you gave him.
Your parents are just freaking out because this is a strange talent that no one really understands....
I'm the same age as you and tried to get my siblings to try Lucid dreaming but neither had the talent but at least my parents didn't flip out.
I applaude you for trying to spread Lucidity.
Hope the tension ends soon enough for you.
