Nothing.
I had the same dream last night but it freaked me out even though i did have black hair three years ago
Most likely gonna happen in real life
You were probably thinking about similar things before you went to bed.
Just a co-ink-e-dink (well did you have the nasty)
It was good.
I really don't think it means anything, but if you're worried, just don't cheat on her.
From the phrasing of the question, this sounds like a one-way affection. The dream illustrates the uselessness of chasing after someone who does not feel the same attraction.
it depends on how much you think about it
Forget it - people almost never have the same exact dream more than once.
This suggests that there is a continuing bond between you and your ex, NOT because of the dream, but because you continue to share intimate conversations about your dreams. The dreams as such mean nothing at all.
It simply means that the two of you have been thinking about similar things and share the same concerns. This is not unusual. Moreover, if you carefully compare the images, actions and other factors in the dreams, you will find they have many differences as well as similarities.
This means that you probably think about this person a lot, and that you care deeply for them. It is natural to dream about the things or people that occupy your thoughts. Your dreams do not mean that the person is thinking or dreaming about you.
