I recently posted this on another forum in response to another poster. I thought you fellows might like a read as well.
A few years back I was staying up at the cabin for a few days, just me and my black labs, Snoopy and Jake. Late one evening, about 2am, I awoke in a terrible fright. I was laying in bed on my left side, so I was able to look directly down the stairs to the ground level. There was a dark shape coming up the stairs. Now this cabin is in a remote area, about 60 miles south of the Canadian border, and it was a moonless night. It was so dark you literally could not see your hand in front of your face. Nevertheless, there was something blacker than the night coming up the stairs towards me. I was quite literally paralyzed, I could not move. I also felt an intense chill, even though it was late summer.
An amorphous darkness floated up towards me, and then stopped just short of me. It gained definition on the left and top sides. The darkness had an edge, a place where it definitely stopped and mere night began. The right and bottom edges had no such definition, and the thing's boundaries seemed to ebb and flow, and fade in and out like a black mist. All the while I remained immobile with terror.
Although rooted with terror, I never sensed evil or malevolence, just iciness and "other". I have no words to explain what I felt, it was something entirely beyond my comprehension of emotion. But it was cold, and it was powerful, and it was terrifying.
Then I felt an icy cold hand, as frigid as anything I have ever felt, reach around and grab my neck from the rear, but the fingers did not seem to stop at my flesh, but slipped through the muscles and settled on my bones. Then another hand caressed my spine from top to bottom. I felt this thing was glad I was there, and the thought of what could gladden a thing such as this only added depth to my fear.
Then it smoothly pulled back and began to dissolve into tatters, like smoke in the wind. The pieces drifted quickly to the east and dissolved.
I was left shivering in my bed, repeating the Lord's Prayer over and over as soon as I had recovered enough to gain control of my faculties. It was some time before I could find enough courage to reach out and turn on the light.
