It took a moment or two to remember where I was. It felt like I was in the middle of a dark dream. I felt scared. Why were they all staring at me? The train had stopped just outside Waterloo Station. Another train stopped beside us and I saw the passengers from that train all staring and pointing in my direction. I felt heat rising from my feet up to the top of my head. My heart beating so lousy I imagine it could be heard around the carriage. I felt my ran my hand over my face. Perhaps a big spider had landed in my forehead. I took the small vanity mirror from my bag and opened it.

Then I realised what the stares were about. My face had turned green. It must have happened while I slept. But how and why?
