How does a place get haunted? What is haunting?

First of all, ghosts are real, but they aren't real in the sense held in the popular imagination.

Let's take a house that is, say, one hundred years old.  Families, relatives, friends, etc., occupy the house over time.  Something happens that creates a tear in the energy; most often, someone croaks it in a bad way.

Using a rock to store excess anger, stress

Stress that hits the digestive, stomach, head, shoulders, and neck areas usually has to do with anger and the inability to express it for whatever reason.

Sometimes breaking your reaction patterns with people in your life creates a place where anger at the previous position tends to ball up.  That creates a pocket where you would normally have stretched out anger at someone, but now you find that it is still being created but has no place to go.

Twilight threw shadows up the hills like dark bony fingers.  Watching the growing, slowly moving shadows, he saw them creep into the edge of the trees like a dark hand insinuating itself into a living glove.

The darkness seemed to grip the earth, seizing it away from the sinking sun, stealing the light, carrying it into the forgetful sleep of an approaching night.  He settled back slowly on his heels, feeling the first coolness of the approaching evening flit about his face in the light breeze.

The day had been hot, hotter than most.  He shifted his position to sit more comfortably on the flat stone he had perched on to rest.  He took off the rough gloves and looked thoughtfully at his hands, inspecting the new blisters and old calluses, which the gloves were supposed to prevent, but somehow never seemed to do.

Once you're in the maw of the beast, very little will work except to just grab on with all four sets of nails and your teeth and ride the bastard out.

How do you combat depression?  It's the little things that count first.  I know, everyone wants the big stuff, the whole enchilada, let's save the universe, etc.

That always reminds me of the Chinese prayer I have been mindful of all these years: "Lord, please reform the world, starting with me."  Depression starts in small ways - you just don't notice it until it looms up and smacks you in the head.
