Only when I am very tired. On the bus from Atlanta to New Orleans I had been up for around 28 hours and had only one or two short naps, and I thought I saw giants playing in traffic. Luckily I knew what was happening so I shut my eyes and made no mention of it.
Giants Playing in Traffic?
What kind of music do they play?
That saound like the name of a band.
They were about 20 feet tall and were doing amazing gymnastics. That and hearing people say my given name even though nobody knew even my first name, at that point I got as comfortable as I could and slept in between bus stops. (I was awake for so long because aside from a few occasional rude people, I had to keep track of when transfers were and I have a tendency to sleep through things.)
