Yume no naka futari de ita yo ne
is translated in a page as
In my dreams, we were together
I don't understand the meaning of the particles here, plus where the 'together' comes from. Yume no naka is 'inside of my dreams' I suppose, futari would be 'the two of us' and ita the past of iru which would be 'were' but where is the 'together'? What does the yo ne adds here? And de is supposed to be a particle that indicates the place where an action happens, but here is after 'the two of us'?
