I showed some stranger my ass...

I'm at Dillards looking for a dress to buy for some party that night. I spot out this nice, long, black, short-sleeve dress and take it into the fitting room with me. I pull down my pants and see that I'm not wearing any undies. I look in the mirror and see my bare ass, and my ass looks purple and wrinkly. I gasp. Just then the dressing room attendant opens the door and stares at my rear. She says, "Not very nice." I push her out and shut the door behind her. As soon as the door closes, I wake up.
I go into the restroom and look at my butt. It's not purple and it's not wrinkly. I'm releaved.
