Well, let’s separate 2 issues. First, those kinds of dreams are common and don’t mean anything.

Separately, your boyfriend has been a bit more moody and distant lately? And is this an online relationship, meaning not in-person? If so, I’m not trying to be a dick, but you don’t have a perfect relationship. If you don’t spend much or any time together in person then I promise you, this is not a relationship, it is a fantasy. You will understand the difference when you have a relationship where you do spend everyday time together. If it seems “perfect,” it’s because you two are on your best behavior without any of the everyday shit on display.

And yes, if you sense a change in behavior from a guy you’re involved with, it’s usually because they are indeed pulling back. I suppose anxiety could make it hard to trust your gut, but that’s usually the situation.

But before I go too far down an irrelevant road, is this an in person relationship or not?

He very well could be feeling exhausted / moody / distant as a result of having to do all this reassurance. If you can’t stop with that, it might be time to see someone about your anxiety. It’s interesting also that you said your relationship is “perfect,” rather than great or loving or nurturing. Are you a perfectionist? Is your mental health dependent on things being perfect?
