Bridger's Oneironautic Expeditions

I'm arriving at a house in a neighborhood where an old lady greets me and takes me inside. Passing by the pantry, I notice a large cake inside. Straight ahead, I also see part of the same cake floating in a water jug. She asks me if I would like anything to drink and I politely decline. Seeming like she wants me to drink, she asks if I'm sure, and I say yes. I'm now suspicious if she's trying to get me to drink because the water's poisoned somehow by the cake. After refusing twice she still ends up pouring a glass from the jug and tells me to drink it. I threaten her by grabbing her face and saying something before walking out and leaving in my car. On my drive home, I get pulled over by a cop car. I roll my window down and the female cop tells me that the lady I was with was some kind of killer and just wanted me to know.
