The Mental Aberration
As John entered the monster's mental world, his own mind experienced some effects.
John felt a tremendous pain in his head, and at the same time, he heard a series of sounds that were not human. These voices seemed to be pleading with him or perhaps threatening him, urging him to leave quickly.
After enduring a bout of intense noise, John finally managed to reach the monster's mental world.
The primary difference between the mental world of a monster and that of a human was its constraints.
The biggest difference between the monster's mental world and the human's is that the monster's seems to be filled with limitations.
In the monster's mental world, colors don't represent different emotions but different powers.
Each monster is composed of different powers, meaning each monster has its corresponding master.
In the Horror Amusement Park's monster's mental world, the predominant color is gray.
