Odd that you mention that...I've been smoking every night before bed for the past 4-5 months, and a few days ago on the one night I didn't smoke, I had a lucid dream. It was nothing much, really short, I was flying in blackness haha, but it was amazing. I'm thinking of taking a break soon, just for a week or two. I haven't felt dumb or anything, I'm just in my head way too much. And I can't seem to express myself as clearly as I could around 6 months ago.
