<human>: This situation is probably immature and silly but I need to talk about it to people I don't know. 

My friend Jane and I work as counselors at a camp during the winter. We also attend university together. We both study writing. A couple months ago, I had a pretty outrageous and very vivid dream. As one of the nighttime activities in our camp, we do a storytelling activity. I told a story that basically detailed the dream that I had, with some extra content to make it more entertaining. It was funny and silly. 

Anyway, Jane (without telling me) basically entered my story into a short story writing competition and won a $500 award for "most inventive". The award was basically for creativity & originality of the idea, focusing less on elements of writing structure or prose, etc. Just for the idea. I found all this out because, although I did not enter the contest, I was reading through the winners of the competition (they post the stories online) and found her name. She didn't even tell me she submitted it; she actually said she was not going to enter the competition this year. 

Am I wrong for being a little angry at this? I don't properly know how to gauge my feelings.

Can you give me a shortened version of the text?
<bot>: I told a campfire-esque story about a dream I had. My friend wrote out my story, sneakily submitted it to a contest, and won a prize for Most Inventive
