The poem harks back to the time I was staying at a rehab in Bow, East London. I went out for a typically aimless walk and found myself in one of the many railway arches in London (and the rest of the UK)
It turned out to be an incredible experience, more so, I think, because it was unexpected. It was like slipping into an alternative reality. A truer reality in my opinion. This took place in the early nineties. It wasn't until the early noughties that I wrote about it, realising in the writing just how much I recalled of it, and how impactful it was.
