I would interpret it as a confirmation of your love and feelings for each other (the hug), after he recognised you since you say that you have changed your look dramatically.

The gifts may be those that a true love or partner may buy (diamonds are a forever item), and the not talking to you or shrugging you off may be a 'lover's tiff' if you will.

That is how I see it. I think you both miss each other, and there is much unfinished business (a deep love) between you, and that is why he comes to you in your dreams. That is how you two communicate with each other, as he doesn't know how to come to you any other way.

Does this help?
