In the silence, the surrounding environment started to change.
An individual's perception of the world was built upon the combination of many senses.
Sight, hearing, smell, taste, touch, as well as other uncategorized senses, like Negary's field of perception, or the spiritual sense that some exceptionally talented psychics were born with.
The various senses allow an individual to perceive the world in a certain way, but when one of these senses go missing, this perception would be distorted accordingly.
There are things that we might not have ever paid attention to, but it didn't mean that they don't exist.
They simply exist in different environments than we do, which made mutual communication difficult, or even impossible.
Conversely, when an individual was able to perceive these things through one or more unique senses, it meant that their 'worlds' had gotten closer to one another.
