I took one step into the chapel. As my second foot crossed the threshold, I felt it. It was as if someone had taken an invisible marker and drawn a line straight down the middle of my body, from my head to my toes. The left-hand side of my body was completely tingly, like my foot had been asleep, except it was the whole side of my body. The other side was completely normal. What was going on? Was I having a stroke? I moved my hand. It was fine. I took another step.
