In a floating world

I am on Tower Bridge. The one and only Tower Bridge. If I shut my eyes and closed my ears I could be anywhere, asleep in bed, on a beach in Bournemouth, but when I open them I can only be in one place - Tower Bridge. How strange that this vessel of mine, this collection of limbs and darkness that contains me, or the essence of me, or my soul, or whatever, how strange that this container, this transporter, is on Tower Bridge. There is no bridge like this in the universe, this is the one from the pictures, a landmark, an attraction. Of course no two places are the same, that's obvious, otherwise they'd be the same place, but somehow these landmarks have a way of underlining this observation, bringing it out of the background. It's just more noticeable here, because in the whole of the universe, this is the only Tower Bridge; it's unique, totally isolated from all other things. And I stand on it. And I cannot change that. When I close my eyes I become a breath in a dark place, I disappear from sight. I open and I cannot believe I am truly here. The more I think about it the less material it becomes, it fades from sight like smoke in the breeze.
