I wake up to a dream of losing my way in a building, running through long corridors, up and down stairs, always the wrong way to find the exit, the wrong floor, the wrong staircase, the wrong door, only to find myself on the roof, or deep in the cellar, and I’m floating, slowly and in control at first, but I know what’s coming next, and I start to panic and struggle as I flail about, untethered, rising too high, my heart is pounding, fist pounding on the glass which shatters and cuts me and I wake into another dream.
