I had a dream...tell me what it means?

First let me explain to you who the people are. I work in a library, and the Librarian, we'll call her Jane, has a daughter named Brenda. In the dream I was Jane, but I didnt realize it until the end. As Jane, I was standing in this building, looking out these gl sliding doors and saw Brenda jogging outside. As Jane I took a picture of her. Brenda later comes in the building to look at the picture and I get a glance of Jane, I guess to show me who i was and I can hear her talking finally and realize that i was her.
