Well I have another view of this dream problem. Well I will have time like this all the time. It can be one of three things.

1 She may have some kind of feelings for this person and doesn't realize it. People can have some kind of feelings (love, hatred, empithy, ect.) and not realize it.

2 She is missing a big sign in the dream and know it is missing but can't figure out what it is.

3 She also may not be able to think about any thing else when she is trying to go to sleep so she has that image in her head wich will result in that dream again.

Hope that helped, happy dreaming!
