Feet in a dream usually represent grounding -- how stable your foundation feels, and which direction you're actually moving in. Feet that won't move or that ache can point to hesitation about the path ahead, while walking with ease often reflects confidence in the direction you've chosen for yourself.
The Superior Planets are most efficacious; the inferiour are weak, and easily do suffer by the Superiours, and receive good or ill from them. - William Lilly (1602.-1681.)
