I had a dream a month or so ago that I was being chased by paramedics and cops because someone has called crisis on me. I would get caught but get away and keep running. Eventually I ran into the culinary room (I was at school) and grabbed a knife...anyway that shook me up for the whole day. It was toward the end of a slightly depressed episode. I thought the same thing, that maybe I was going to go so far down I'd end up in that situation...but after a couple of days I cheered up. So it might not be foreshadowing, just an outlet for emotions you may not be aware you're having.
