Okay, I am from the southwestern part of Michigan and am only 17 years old. 

I am writing to you to inform you that on the Sunday before memorial day May 28, 2000 my two friends and I were in the basement of my girlfriends house. She claims that there is a demon in her house, along with the fact that the house is built on an old Indian Burial Ground right near Clark Lake around Jackson, Michigan, she also says that the demon has plagued her since childhood. 

It usually appears to her in the form of a dark cloud and moves toward her, then she feels it grab her and she goes numb ands starts shaking or convulsing or something until she passes out. 

Okay anyways we were in the basement all laughing later that night (one of the people just went home) and all of the sudden the lights in the basement shut off, not by a light switch, but by the fuse box in the separate room in the basement ( which could only be accessed by someone who had to walk in front of us and open another door, along with finding their way to the staircase across the room) All of the sudden my girlfriend goes "everybody get upstairs now.....I am serious, everybody get upstairs." I understood immediately for I felt my stomach twist, the hair stand up on my neck, the temperature drop and it felt like I was being breathed on all over my body with something weird like being breathed on by evil lips or breath or something. Other than those feelings I started to get the tremors in my whole body for no reason, it was as if I was so scared that everything started to shake. 

Since I was young I have always wanted to see or feel a ghost. This experience has made me never want to even read about them but for my girlfriends sake I need to know about what it was?

Sincerely,

one very frightened guy
