Funny you should post this now... I just started dream therapy. As I understand it, your dreams will stop once you have worked through that particular issue. The whole dream therapy thing is still a bit sketchy to me and I haven't completely bought it yet, but if the dreams continue it means that whatever is bothering you is still stuck in your subconscious. Sleeping in your t's office can also mean that that is the one place you feel safe enough to close your eyes because we are most vulnerable when we sleep. Have you discussed this with your T yet?
