The way one interprets the information around oneself is

The way one interprets the surrounding information is related to one's values, beliefs and past experiences.

Each person filters incoming messages through this personal frame of reference.

Saying interpretation is always negative treats a variable outlook as a fixed gloom.

Saying it is always positive likewise forces a single fixed tone onto varied perception.

Calling it always mysterious denies that interpretation follows knowable personal grounds.

This is why the same message can mean different things to different people.
