Here are some (not very serious) theories that came to my mind recendly: Which teory is most possible in your opinion? (Remember, or of them are jokes.)
 * 1) All events in the show are just very long, crazy Dipper's or Mabel's dream.
 * 2) All events in the show were imagined by main characters
 * 3) All paranormal acivity is just Mabel's hallucinations caused by Smile Dip.
 * 4) All paranormal activity are just people/animals in costumes and special effects.
 * 5) All that happened in this cartoon is based on Alex' and Ariel's Hirsch real experience, but Alex says that no, because no one would really believe this.
