Hey darl.. I have no real response except to say that once i dreamed that Dh cheated on me with me.. so i kind of get the double you thing in the dream.. fo rme i took it as "i" was paranoid about his faithfullness... but in reality i was telling myself that "i" (the other me) would be the only one he would ever be with....

So not sure how that works for you.. just googled a bit and didnt find too much, just that "two of you" could either mean its a positive and negative of yourself.. So maybe the "positive you" is reassuring the "negative you" that one day (sooooooon!!!!!!) you will be experiencing this for real!!!!!!! Which actually kind of works and seems in the dream that you have been convinced.. as the You 1 knows that its your baby even though "you 2" birthed her. So the "you 1" may be the neg you who has now been convinced that its all ok and it will happen....

Rambling now!!! Hope that helps!!!! :-)
