I had a dream that I was taking chemotherapy. While I was in the chair with a needle in my arm, they sent the chair down a rail to the roof, where it turned into a roller coaster. When I got back in they explained that they did it to entertain the patients while they were taking the therapy. I asked, "But don't chemo patients throw up?" And the nurse replied, "Only four or five a day".
It wasn't a fun dream.
