When I was at the peak of my manic episode leading up to hospitalization, I could hear people talking on the 1st floor when I was on the 2nd with my door closed. I went down to make sure there were people there and there was, having the conversation I thought I was hearing. This convinced me I had superhuman hearing. I saw shadows while driving and thought they were holes in the road and would swerve to avoid them. I saw waves of light that had human-like appearances convincing me there were ghosts in the house. When I was in the hospital I looked out my window and was sure I could read the numbers on the tractors half a mile away.
Any shadow was also a person or animal sneaking up on me and I would swing around to face them and find nothing there. Any siren was the cops or the men in white coats coming for me to throw me in jail or take me to the looney bin.
