I had a dream the other night in which I could feel a slight pain in my heel... as though I had stepped on a pin. I was looking at the bottom of my foot and saw a glimpse of something shiny. I was trying to extract whatever it was, and digging away at the skin. Once I managed to get hold of it, I started pulling it out - and pulled an entire key out from my heel. It had been pointed upwards. I had no idea how it had got there or what it was the key to. Any ideas what this dream might mean?
