I have had occasionally some kind of terror in night when I was a child. In my case, it was more caused by the fact I was not fully awake.
I remember once I awakened in the middle of the night, in complete darkness. I searched the wall, and instead found that what I was touching was completely unknown, and I started to panic. I screamed, and one of my parents came to see what was happening. When the light was lit, I realized that I was indead touching the wall, but I had awakened turned about 45° than usual, and because of this I hadn't recognized it was the wall :d oh: Once fully awake, I couldn't believe I had been completely lost for a mere 45° rotation
I later learned to cope with such "night terror" by waiting a while to be sure I was fully awake, then try to find concrete evidence of what caused me terror. I never found any

The real sign that someone has become a fanatic is that he completely loses his sense of humor about some important facet of his life. When humor goes, it means he's lost his perspective.
