Dipper Pines made the worst mistake one could ever make. The one he would regret for life. What mistake is that you ask? The mistake of making a deal with the dream demon, Bill Cipher. Bad things happened. Pain increased like crazy. His family, his friends, they were scared-no-terrified of him. You may ask: "Why would you make a deal with a demon? Haven't you heard the saying 'Don't Make A Deal With The Devil?' Haven't you learned your lesson?" He had no choice. He didn't want this to happen. This isn't what he wanted. Bill had a way of making things happen, getting things he wanted always, and this was one of those things. "Pine Tree, you're truly doomed."
