Could you be more specific? Are you supposed to write a short story using these words? If so, the first thing to do is make sure you understand the meaning of the words. If there are any on your list that you don't know, you need to look them up first.
I might suggest this plan to you. After you find out what the words mean, arrange them by part of speech. For example, put all the nouns in one column, put the adjectives in another, the verbs in another, and the adverbs in another (also note that depending on how words are used, they could change their function or part of speech in the sentence - but we are not doing grammar here so that is not the most important thing).
Now look at the words and think about them for quite some time. Do they suggest any kind of story to you? For example, when I consider the word "aghast" and "chagrin" and "flinch" I associate this with something surprising that has happened. Perhaps this can suggest some sort of action for you to write about. What might be an event that would cause a person to act "aghast" -- or what might happen to cause someone to "flinch"? Since Halloween is coming up, perhaps you can write a story about that - some of the words seem to suggest a kind of eerie plot to me. We cannot write your story for you, but I will give you an idea of what I am talking about here to get your own creative juices started:
My brother has an uncanny sense when it comes to choosing his yearly Halloween costume, but this year, his costume left me aghast. He had ingeniously assembled a box full of old rags and had wrapped his body as a mummy. The effect was eery and realistic, but what happened to him as he walked through our neighborhood in his costume changed our little town forever.
