A window in a dream often reflects perspective -- how much you can see of a situation, or how visible you feel to others. A clear window can point to clarity or opportunity coming into view, while one that's broken or blocked may name a fear of being exposed before you're ready.
It behooves the astrologer to consider the time in directions of the planets; but in the fixed stars it is not so needful. - William Lilly (1602.-1681.)
