Final answer:
The excerpts provided offer scenarios of different frightening experiences but do not directly confirm whether the subject panicked after a shark attack. They highlight typical responses to fear, which may suggest panic in such a situation.
Step-by-step explanation:
The given excerpts from various narratives do not conclusively indicate whether the subject panicked after a shark attack. All the excerpts provided relate to different scenarios involving danger or panic, but they do not directly answer the question posed. However, discussing the physiological effects of fear, such as the "racing heart, rapid breathing, clammy hands," suggests that panic is a common response to dangerous situations, which could imply that the subject in question might have experienced panic during a traumatic incident like a shark attack.
