[Luckily, (or maybe unluckily) Dipper did not come to that conclusion over Oscar, but rather himself. He's thinking back now, to what happened in the bedroom. The way the room felt like it attacked him. It was easy to think at first that it was maybe something the town had done.]

[It's easy to blame the town, like it had been easy to blame Deerington, but this was different. After all of it had settled Dipper knows the truth. It had come from him.]

[He'd done something to the room, and it had affected not just him, but his family, too. And here they were inside this dream that he was having.]

Yeah.

[He looks down at their hands for a moment, and then back up at him, concern and ...fear? In his eyes.]

Oscar, I did all this. Before I fell asleep- I walked into that room and it was like it attacked me. My memories came back, but it felt like I'd soaked in every nasty feeling associated with that room and it was like something burst out of me. Everything went crazy, like October came back.

Whatever it was, I did it and I somehow dragged my family into it with me.

[He's the one with Bill powers.]
