Can someone tell me what this means?

In our school production of "Annie Get Your Gun" i play Dolly the second female lead and well i dreamed one night after practice that i was in the wing fixing to go on but before i went on the to main leads Annie and Frank were in the scene where they are suppose to have a big pionate kiss. Well for some reason i felt extremely jealous which isn't me at all. It wasn't because Annie was kissing Frank. But because Frank was kissing Annie. It shocked me because she is one of my friends. And its just weird to think of her in that way but what happen next was the scene started over Dolly was the one kissing Annie. Its just confusing because this is e repeated dream.
