Illumination, and introspection are in this dream. The cat and her kittens are in hole in the ground, beyond illumination, as was the little boy. These things are within you just, below your conscious mind. You looked within using the cell phone light, a light that only you carried. You saw the cat and her kittens using your own mind (light). The cats were consuming the helpless little boy. (a part of you that feels helpless). Those who you look for for help were not paying attention to you.

You could not scream for help because you no longer feel helpless. You feel ignored, yet you you have a wild side, that takes care of her kittens. I don't feel horrified by your dream. Instead I think of the Sacred Forked Tree.
