A couple of weeks ago I went to bed with a stabbing pain in my foot, during the night I detached the affected foot-it was a twist off bayonet type fitting-and with a penknife removed the corn that was causing the trouble. When I awoke I looked round the bed and was glad to see that there was no blood on the sheets, as I have been known to act out my dreams*, finally the really weird part is that I woke up properly, having just dreamt about waking up.
*On a previous occasion I dreamt that I was climbing a tree but I fell out when a branch broke, I woke up with blood pouring from my head because I had pulled on the headboard and broken it onto my head, 7 stitches.
