You mentioned "hallucinating smells." I'm not sure I hallucinated smells when I last water fasted, but I DO recall experiencing a sense of smell on hyperdrive. I could literally smell people across the room! And...I could barely attend any social functions because the overpowering scent of hundreds of people made me nauseous. It was like a wall of odor! Anyway, my experience might be normal for others who have water fasted--it's been awhile since I've read some of these posts.
