You ever think about how the dead drastically outnumber the living?
Even if one out of every 10 people became ghosts, thats a lot of spirits roaming around the world.
Especially old lands...that have a lot of history to them...
...a lot of death...
......The spirits of the dead tend not to adhere to the boundaries of our physical planes.
And they were once people, you know. People tend to be a little curious.
Tend to wander.
Why...the shadow in the corner of your room is just curious. It knew what it was like.
To be alive once.
....How it wishes to have that comfort again.
Watching you. Hearing the blood rush in your fleshed husk. A mere vessel to its eternal gaze from the ethers.
How cold is the hand that longs to touch the warmth again. Warmth of your skin...of your living hide.
How it longs to be whole again.
Maybe you can help it.
Maybe you can't.
As you are, the spirit once was. As they are, you shall be.
