Hey there,
I wouldn't be too concerned about the dreaming stuff, considering that's not totally in his control. Three times on separate occasions is a bit strange though since it's seemingly quite common.
Regarding the speaking to her on Facebook thing, I can understand why that would bother you. Although he technically hasn't done anything wrong by speaking to another female, there's definitely some cause for concern. What has been the outcome of your arguments? Has he understood that it's bothering you and tried to help you understand and relax about it? Or is he simply just brushing it off as a just friends kind of thing.
From experience as a guy and having male friends in very similar situations, as you can imagine it's a popular situation for both women and men, it's possible that he's just attracted to the female he's being speaking to on facebook and maybe she's flirting back. That doesn't mean he's cheating on you, he might just enjoy the attention of another woman as he feels he's still in the game, so to speak.
You didn't give us too many details to go off, for example, where does he know this girl from? Did they just meet on Facebook or does he know her in real life?
Anyway, best of luck in your situation!
Jake Collins.
