"Creepy" definitely falls in line with Pretty Little Liars, and writer, Andy Reaser gave a recent teaser to a fan on Twitter involving a bed in season 3 episode 14, "She's Better Now".
@livingforhale well... there is a really creepy scene on a bed.

Whose bed might this be, and what's so creepy about it? It could have something to do with Spencer (Troian Bellisario) and Toby (Keegan Allen), now that we know the truth about him, and Spencer still doesn't. Then again, it could have something to do with Mona (Janel Parrish), as she's released from the sanitarium. (Could it be she's "released" of her own accord? Wouldn't be too much of a surprise.)
Andy also cleared up the little girl ghost Hanna's mom, Ashley saw on Halloween during "This is a Dark Ride"...sort of.
@_titi2105_ I don't see how... it would involve a serious disruption in the spacetime continuum

If not CeCe (Vanessa Ray), then that whole Alison-twin theory is looking more and more likely.
You can talk about that scene, and the "creepy" one on the bed, below in the comments.
