It late at night and the supermarket was closing up soon. We were about to leave but I wandered off to another section of the store until I ended up in a mostly empty area. Along the perimeter there were large windows opening to empty storage spaces. I walked along the metal frames until people called my name from above. They were hanging out on the top empty shelf and seemed to be enjoying themselves. I climbed up and landed onto a bed with dark grey sheets. There was a window on one side to the morning street outside.
