The dream demon’s children?

Dipper and Mabel were in this house-like pyramid with their “dad” Bill Cipher, the whole world was turned upside down. Gravity was not existent, everything was just.. the opposite.

The twins were used to it though, Dipper and Mabel both loved to float around in the house while time was nonexistent. The Bill Twins were of course raised greatly by Bill, he raised them to play mind-playing tricks on the humans.

Dipper was reading the journal Bill had stolen from a man his dad considered a “ally”, and he honestly found it interesting. It seemed like his dad tricked this guy to build a portal so they could reign free soon.. some day.
