Every time my aunt comes to visit, she tells us an anecdote about her childhood, such as the time when she dressed her dog in her baby doll’s clothes.

An anecdote is a short account of an amusing or interesting incident, often from someone’s life. The story about dressing her dog in doll clothes is a personal, amusing incident, so “a short, amusing story” is the best choice. It is not imaginary or necessarily a joke.
