Angst in the night

A nebulous soul was looking for a body to possess,
I was in a cocoon of dread pressed down
could not breaths
The thing, this being was stealing lungful of air.
Terror is a kitchen in a basement, with a floor made
of rough planks from sunken ships, white as the bones
of dead mariners
It has no smell,
Colourless,
And bloodless.
I got up and lit the night- light, the room was ice cold
the dog came with her body gave me warmth.
This misty being had tried to take my body its hunger
for life was endless.
In the morning sunlight warmed my face
my dog had come from the past and saved my life.
