After ending its latest season last week, "American Horror Story" is teasing possible themes for its Season 7. Some of these themes include a ghost ship, a story from World War II and Lady Gaga's Scathatch.

The official social media account of the series posted a clip titled "Sweet Dreams," which has footage of ocean waves with the stick dolls from the North Carolina farmhouse, USA Today reported. The ominous video had a caption saying that the monsters are all gone. This could be a reference to the model ship that fell over in Season 6.

That clip could mean that Season 7 will bring fans to the ghost ship that they have all been gossiping about and it's certainly not cancelled.

Ryan Murphy, the show's creator, said he will not keep secrets from the audiences as he divulged some hints from last season's "American Horror Story: Roanoke," The Hollywood Reporter reported. Chapter 9 showed a model ship that tumbled conveniently to the spotlight, which hints a Ghost Ship-centered story.

However, Roanoke also featured references to government conspiracies and military themes, like how Dylan served in Afghanistan. Season 6 also has references pointing to World War II events. With the characters from "Freak Show," this could easily imply that the events will happen in the past. Fans could remember the Confederate Flag that the Polks kept in their home.

One more theory is the witch of the wood Scathatch played by Lady Gaga, who appeared for a while in the show. The show runners could explore deeper into her backstory. She is an important part of the lore of the "American Horror Story" being the Original Supreme.

There are reports that the anthology may follow her ocean adventure story. Roanoke gave a little hint on how Scathatch came from England and became a stowaway ending in America. She became deadly and was subjected to a witch hunt.
