Madness of the Mind

Ever had something happen that you weren't sure was real? Seen something that was impossible so you just shrugged it off and forgot about it? Ever had someone act so strangely that you were a bit afraid, but shrugged that off too, and then later remembered and wondered if it actually even happened? If you were mad, would you know it? If you would not know it, how do you know for sure that you aren't mad right now? See if anyone around you, someone close at hand, resembles any of the people in these stories; perhaps YOU resemble some of them? Question is, and always will be... if you were mad, would you know?
