I dreamed that my friend came back from the army and turned into a yellow dog. He can't talk, but he keeps crying at me and I cry at him.

First, you miss him too much, because he just joined the army and just left. You must be a little unaccustomed.

Second, you don't know much about the army. You just heard some people say how hard the army is, so you think your boyfriend is hard in the army. It's not what you think. The army has a life of troops, and there is also a rich life while training!
