I'm watching TV in a room with a bunch of people. My middle sister is lying on a couch that's directly under the TV, facing away from it. I hear a moan from that direction, but it takes a couple of seconds to register that that was not a usual sound at all. I stare at my sister, wondering if she's dying from some wasting disease. I wonder if I should ask her if she's okay, even though that would disrupt the movie. Then I realize that the moan sounded almost sexual. I'm not sure. She's covered in a blanket, so she could be. . . . I avoid looking at her directly, but from where she's putting her hands and the disgusted sounds the rest of my family is making, it seems like she's probably masturbating.
Later, the main plot has taken the family driving in a car to another place. We get out and I start talking to one of several men standing outside in a group. It's an important conversation, and our discussion basically resolves the main plot. Towards the end, one of the other guys in the group starts muttering audibly to himself. I can't understand what he's saying, but it's distracting, and I realize, delightedly, that that's the point. It's a joke that when you mutter to yourself, you never know what kinds of conversation you might be interrupting. Or that no matter how important your conversation is, you might still get interrupted by a random muttering dude. Either way, it's funny. We all start laughing, and then, to my incredulous surprise, we go in for a group hug. We pretend like we're going to exclude the muttering guy, but then we let him in. All in good fun.
Later, all that's left is to wrap up a few loose ends. My middle sister came with us because she wanted Dad to buy something that removes semen from a uterus. Turns out there was a secret passage that comes up underneath that couch. One can reach it by going through the false back of a cabinet under the TV. So she had actually been having sex with some guy who came through that passage. We never saw him, but when the truth came out, we also found out that she's worried she's going to spill some semen out from the way it came in if she doesn't get some kind of tool to remove it in a controlled fashion. So now that the main plot is resolved, Dad got her some kind of wooden thingy that looks a bit like a spool that should apparently do the job. That ties things up nicely, so it's time to wake up.
I open my eyes into my dorm room and check the time, to see if I woke up in time for class. The clock says the time is 18:90. Converting from military time, I'm shocked to find that it's already evening. Wait a second, that kind of ridiculous lateness usually happens in dreams. And there aren't ninety minutes in an hour. Hah! Nice try. I manage to wake myself up successfully.
