For the past three days,I've been having the same annoying dream of someone knocking on the door. At first I thought it was just a couple pranksters in the building,but that theory was challenged when I woke up from a deep sleep and ran to the front door to answer the knock....and Terry who was working on the computer at the time, questioned me as to what I was doing. I told him about the dreams that I have been having and that I thought I had heard it again just then. He said he hadn't heard a thing, so I know it's just a reoccurring dream...but why? What does it mean?
