School (Monday)

I look like I'm on the way to trade on the market in this warm morning light. What was I thinking? My feet still drive me along the wet streets between the red shades of the suburban homes. The other shells are perfect for scavenging, and now only the expensive ones are working, but this is not why I am here.
Around three years ago I starting seeing these floating islands in the sky and didn't then realize that she was the only one that could see them. I thought something was wrong with me and the islands were hallucinating. What am I? Am I human? And why do I see these floating islands?
