This bizarre disease is spread by touch, and cause its victims to fall into a delierious state of mind. The first day of the illness, leaves the victim with a bad feeling, an intense paranoia, and causes the victim to see and hear things just out of sight, or in their periphreal vision.
The second day leaves the victim unaware of their surroundings. Some even forget who they are.
The third day, the hallucinations increase, bot in quantity and in quality.
The fourth and final day of this disease leaves the victim entirely mad. They act out in violence and insanity, literally walking in a world of nightmares made incarnate.
