A Fog

It would be the first time I would ever experience it. I stood in my room and felt this unfamiliar twinge in my head. I felt as if I had somehow been transported to another place. It was such a strange surreal floating feeling. I didn't feel sad or upset, just anxious. I tried to fight the strange feeling as it took over my head, closing in on me, almost choking me from its sheer force, and making me submit to its power. I stood there, silent, scared, frightened of what this force was. I was in such a fog, I felt that I would fall prey to the fog that hung over me, and then as quickly as it started it was over. What had just happened to me?
