It originally aired on the Disney Channel on July 12, 2013, and was written by series creator Alex Hirsch, alongside Matt Chapman and Tim McKeon, and directed by Joe Pitt and John Aoshima.
The series follows twins Dipper and Mabel, who live with their grand uncle, Grunkle Stan in a tourist trap called the Mystery Shack in the fictional town of Gravity Falls, Oregon.
Dipper Pines (Jason Ritter) with his sister Mabel (Kristen Schaal) and friend Soos also go into Stan's mind to stop Bill from finding out the combination.
He also engages in various antics in which he pulls out of Mabel's mind the movie characters that she was thinking about (Xyler and Craz) that follow them until the end of the episode; he also blasts a (non-fatal) hole in Dipper's torso.
Within seconds of Dipper, Mabel, and Soos returning from Stan's mind, they discover that Gideon's Plan B was to break in again and successfully steal the deed — only this time, he simply used dynamite to blow the safe open, without needing the lock combination.
The episode "Dreamscaperers" was written by Timothy "Tim" McKeon and Matthew "Matt" Chapman under the story of series creator Alexander "Alex" Hirsch.
During the scene where Bill is summoned he strikes out a number of images on his body, like John F. Kennedy, UFOs, the Aztec calendar stone, the Apollo Moon landing, Stonehenge, Giza pyramids, crop circles, etc.
The characters Xyler and Craz from the fictional movie "Dream Boys High" are based on 1980s cartoons and teen films produced in the United States.
Additional voices include Linda Cardellini as Wendy, Greg Cipes as Craz, John Roberts as Xyler, Jennifer Coolidge as Lazy Susan, Grey DeLisle as Carla McCorkle, Kevin Michael Richardson as Sheriff Blubs, and Stephen Root as Bud Gleeful.

[3] He states that Bill Cipher is the most memorable creation in the episode describing him as "the Eye of Providence wearing a top hat", also stating that "the writing and Alex Hirsch's voicework hit a fascinating balance with the character; Bill is capable of genuine rage when his plans don't work out, yet there's always the sense that he's just toying with the kids, allowing them to temporarily beat him because it amuses him".
