I was in a mysterious place. The place was like frozen in time. Everything was black and white. I was running on a dirty road with lots of stones and holes. I had long brown hair and extremely pale skin. I was afraid, afraid of whatever that was chasing me. For a moment I looked back to see what my pursuer was doing but there was no one. Then I came face to face with a door which was not there earlier. It was ajar. I entered the room which was very dark. I could not see anything. I stumbled forward to find myself falling down the step of stairs. I quickly stood up as I reached the bottom of the stairs. I could feel pain from falling earlier. Blood was slowly trickling down my arm where a small cut had formed. I felt dizzy for a second and then the next moment it looked like I was being strangled. I struggled for breath fighting my invisible enemy. I moved forward in the room which seemed to be a basement. Then as suddenly as it had come, the feeling of being choked disappeared.
