All that matters is if you're both on the same page. You're the only ones that can know if you need to put on the brakes. But if you're both happy and comfortable and as grossly in love as ever, then you're on the right track. And, you know, maybe the dreams have something to do with how you're feeling, especially if you guys were getting that serious in them, but it also doesn't change that you've also known each other for a long while. Obviously a relationship is different than a friendship where two parties are "secretly" pining for one another, but I'd figure that it kind of leaves you skipping some of the early awkward getting to know you parts. That's my two cents.
Good, because it probably wouldn't have been okay. I was just pretending to be selfless for a second.
