He was simply being a perk at that point. Nothing more to it. And it was downright rude and insensitive of him to do that.

Your dream had nothing to do with him so he lost interest. Some males are insensitive that way. Selfish. Sorry he did that to you. Maybe express to him that his insensitivity was not cool if that bothered you. Best of luck to you. :)
