Ghost dream

In this dream I am in some kind of boarding school. It's co-ed. It's night time and all the students are standing in a hallway, sitting against the walls. The lights are off and we are waiting in silence. There's some kind of story that everyone knows and is the reason why we are all sitting in the dark. The story is that a long time ago a woman was killed in on of the rooms. Now she haunts the room. There is a game that the students play. They turn off all the lights and sit outside the room in silence for 10 minutes. Then one person and one person only goes inside the room and has to stay there for one minute. After the minute is up, if she hasn't attacked you, the door is opened and you are safe.

So here we all were, waiting for 10 minutes. The time was up and it was time for someone to go into the room. I volunteered. I went in and closed the door behind me. Immediately I saw the ghost. She was up on the cieling, just floating there. Her back was towards the ground (she was horizontal). I walked around the side of a pool table, keeping an eye on her. In my head, I went over what I needed to do. "Ok, stay in here for one minute. If she wakes up, don't move. Don't make eye contact with her either or else she will suffocate me by squeezing me (without touching me)". The seconds dragged on as I waited. I was as silent as could be. Then I heard a voice that could only be described as a creepy old lady voice. "Are you disturbing me?" it asked. It was the ghost. She woke up and rolled around to face me. My eyes widened and I held my breath. I made to move towards the door but she came down and was at the end of the table (blocking the door). She looked kind of like the ghost that was in the movie Thirteen Ghosts (the Jackal without the box on it's head and wearing a dress....google it to see what i mean). I was trapped. I could feel her trying to suffocate me. I then jumped out of the window behind me and ran as fast as I could! She began chasing after me. I ran down a sidewalk and turned the corner. I stopped short so I didn't run into this old lady that was holding 2 brown paper grocery bags and a chihuahua. I then picked up a chain that had two big hooks (one on each end). The ghost came around the corner and I threw one end at her, wrapping it tightly. Then I threw the other end on the bumper of a passing car. She was then pulled away. For how long, I don't know. I didn't stay to find out. I ran off and the dream ended.
