I am on a bus, going to University, with some of my friends. We get off the bus, and someone asks how to get to the Chemistry department or some-such. I suggest taking a shortcut through a building that I don't recognise. Inside, it is much like Marks and Spencer's, only there are arms for sale in place of sensible clothes.
I find a set of automatic doors at the far side of the room. We sail out of them, and notice that there is a 100ft drop, covered only by a steep trellis.I fall through this, only just managing to grab hold of it as I fall. The trellis comes away from the wall and arches until I thud into the soft earth at its foot. I am a little shocked.
