Dream of bedroom, jealous

An old friend who i haven't seen in almost sixteen years "not an ex, just a friend" was standing on the opposite side of the road, I thought she needed a ride so I pulled over to give her a ride, but she said to me " do you know why I'm standing here" and she took off the nice short dress that she was wearing ontope of another dress and she gave it to me saying happy birthday, it was not my birthday I thought in my head, she said I have paid the tailor to make you a more expensive dress all you have to do is pick it up, the dress was for my ex-wife I felt and I gave them to her she accepted it with no question, she wasn't jealous like she usually would, the next thing I saw was that I and my ex were having fun in my bedroom, not sex, fun, and my brother was at the door looking at us, my ex didn't notice him, i did so I short the door at him
