Suspense is a mental uncertainty or excitement as the awaiting of a particular decision or outcome of an event. This can usually lead to anxiety or apprehension.
Suspense can be when one is expecting something bad to happen. It is a combination of anticipation and the uncertainty of the dealing of the event that is waited upon.
Suspense is a day-to-day emotion that happens to everyone e.g. waiting for the result of an exam, waiting for the confirmation of someone's safety, waiting for the result of a film characters action, etc.
It evolves around waiting for an answer verbally or physically and of something or someone's actions.
