Hey, this is a preview of a BillDip fanfic I have thought of :
It had happened again. The dream that plagued him throughout the years played in his mind. The dream was of what seemed to be a man sitting and waiting for someone. Then the other person comes and greets them with a hug. They appear to chat for a while until the dream ends. Dipper has had that same dream ever since he was 4. At first, the dream was very muddy and it was hard to tell what was happening, but as he got older, the dream became clearer. It was the one mystery he couldn't solve. He had put years of research into finding the cause. He would spend nights theorizing, but he only ran into dead ends and more questions.
