As I regained some awareness of my body, I tried to lean my head a tiny bit forward. Nothing moved. It was as though my forehead was pressed against a wall. Something very solid was resisting even the slightest movement of my head forward. I immediately realized that the sheer intensity of my concentration had created a well-defined force that flowed outward from my forehead and curved back to the point in my lower abdomen where I had been concentrating. I know this must sound strange, but it felt like a magnetic field that was so strong I simply could not move against it.
