What is the feeling known as "ennui" associated with?

The feeling known as "ennui" is characterized by a profound sense of listlessness and dissatisfaction. It often arises from a lack of engagement or interest in one’s surroundings or activities, leading to a feeling of boredom that is more than just temporary disinterest. This emotional state can stem from repetitive, monotonous situations, where one feels unease due to the absence of stimulation or purpose. It is not associated with excitement, extreme happiness, or calmness; rather, it is marked by a yearning for greater fulfillment and enjoyment of life. Understanding ennui is important, as it highlights the human need for engagement and meaningful experiences.
