Actually, dreams tell you alot about your subconcious and if interpreted could really tell you alot about yourself. I got a few dream books and its crazy as to what you discover about yourself when you interpret them(I think Freud is kinda ridiculous cuz he believes that most dreams derives from sex). As far as your GF's dream this is the closest thing I got:
Boyfriend
To see your boyfriend in your dream, represents your waking relationship with him and how you feel about him.
To dream that your boyfriend is dead, indicates that something in your own Self that is no longer functional and is "dead". You are not being allowed to fully express yourself. It is also symbolic of your own relationship with that person. Perhaps you need to let go of this relationship.
If your boyfriend is away and your dreams of him involve a lot of touching, signify how much you miss his presence and have him being nearby. The dream is telling you not to take the day to day things for granted. Learn to cherish the smaller things in life.
To dream that your boyfriend tells you that he is gay or that he doesn't love your anymore, represents your own insecurities with the relationship. It may also mean that the relationship is moving to a new level to which you are expressing some anxiety and fears about the changing situation. You may feel left out it in his life or that you are unable to share in all his experiences. It boils down to trust and communication.
