Read the entry, and you know what? I see a little lesson in it.

my "Dream Guide" (not sure if he actually is because I lost lucidity because of him) says to do something, (speak maybe? I'm not sure) you have to make him laugh.
So, you mention the DCs have been somewhat aggressive in your last couple of lds. In this part, your angry brother was coming in the house, and you weren't sure how he would behave. Your dream guide told you to make him laugh. Changing your mood like that is one of the best weapons with uncooperative or unpleasant DCs.
