Dreamcatchers (Item)

The Dream Catcher is a magical item featured on ABC's Once Upon a Time. It makes its only appearance in the tenth episode of the second season.

History
Mr. Gold allows Emma Swan to use the dream catcher to view the memories of Archie Hopper's dog Pongo, in order to prove if Regina has in fact murdered the dog's owner. However, just as magic is about to transpire in the vision created by the dream catcher, Emma drops the item to the ground and it is not revealed that the Regina in the vision is in fact Cora in disguise, and that Archie has not been murdered at all. Therefore, the gang still believes it is Regina who has murdered Archie Hopper.
