Everyone has a little 'mad' in them.

When it comes to the true meaning of life, people of normality become completely baffled. If a normal person would just sit down for a while and straight out think about the true meaning they would eventually lose their mind and would possibly not be able to differ between what is reality and what their pure imagination is showing them. Wrapping your head around these thoughts are interesting at times but are completely limitless. These limits are always tested when psychologists try to help the psych ward patients. By pure opinion and imagination, these patients supposedly have 'learned' the secrets of the world through their dreams and know things that even the smartest people wouldn’t understand.
But I believe that even the best people are a little mad.
