A Thought is a central theme and gameplay element in the game Everything. In The Beginning, it is given to all things in the universe. When the Player walks around and explores the world, they will see thought bubbles pop up and can answer them to learn what the other object is thinking. All objects in the game have the capacity to think.
When exploring the universe, the Player will commonly stumble across a thought bubble icon. They can then travel to the object that has the thought and can receive the thought. The thoughts are usually random, but relate to the overall existential theme to the game.
When the Eye fills up, the player has the option to think for themselves in a similar way to when answering other object's thoughts.
