Jenny and Rune, you guys are too funny.
The Jungian intepretation provided by Estelyn fits the facts of my experience of late; not that anybody's been trying to kill me, but there are destructive forces that are apparently trying to undo the good I am trying to accomplish.
Taking a somewhat objective stance, it occurs to me that a tent is a temporary shelter, sort of akin to one's body. Hmmm.... this is not the first such dream about such a thing....
