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.
The native will be sickly and weak, when Saturn is elevated above Mars; but if Mars shall be elevated above Saturn, he shall be fat and lusty. - William Lilly (1602.-1681.)
