<human>: He says he's been having a dream that he cheats on me, always with the same person (he never told me who). We both know he'd never do something like that, but it really bothered him. 

At first I just shrugged it off, since it is only a dream, but now it's bugging me. I feel like we don't talk as much as we used to...maybe he's been busy, I don't know, but our mutual friend said it's probably because of the dream. He apparently has it often, and he tries to avoid sleeping because of it. She said it made him consider ending things with me, though he says he doesn't want to do that. Now, he just seems so distant.

 I don't have a lot of people to talk to; it's mostly just him and our mutual friend. I have a hard time talking to people I'm not comfortable with, since for some reason I've withdrawn a bit in the past few years. Because of that, it really affects me when I don't hear from him much. I know it's no one's fault but my own that I'm so bothered by it, but I don't know what to do. I don't want to bring the dream up, since it upset him pretty bad last time, but I feel like it needs to be discussed.

How do I confront him about it? Or should I even bother? I'm young and not really experienced in these sorts of things, should I simply wait for it to pass? It's making me nervous and worsening my anxiety.

Can you provide a brief overview of the text?
<bot>: Boyfriend's been having the same cheating dream lately, bugs him more than it does me, but now I feel like we're growing apart, and I don't know how to fix this. Help is much appreciated.
