I had a random dream that I was flushing a vacuum toilet loads of times and I was thinking, "This isn't scary at all." It felt like indifference, though if I was seriously that indifferent to vacuum toilets then I wouldn't have flushed it as many times as I did in my dream.
Anyway that was a very good dream. Sorta makes me feel like I can do anything- even go on a plane for an 11 hour flight.
