Falling is one of the most common dream images, and it usually shows up when something in waking life feels out of your control -- a decision, a relationship, a responsibility you're not sure you can hold onto. It's rarely about an actual fear of heights; it's about the sensation of losing your footing somewhere else.
When a Planet who is a Fortune is in Conjunction with an Infortune, he allays his malice, so that the Infortune shall do no hurt. - William Lilly (1602.-1681.)
