'Pretty Little Liars' preview: Alison pays Spencer a late-night visit

"Pretty Little Liars" has just two episodes left in Season 2 - and in the finale, we have been told "A" is going to be "unmAsked." But before we get to that excitement, "If These Dolls Could Talk" get the Liars one step closer to finding out the truth.

In the above preview video, Spencer is ... having a dream about Alison? Maybe? Or is Alison actually there? It's kind of like when she visited Hanna in the hospital. Alison tells Spencer to look at what's in front of her ... and that she's getting warmer.

And in the below video, the girls visit the proprietor of the creepy doll hospital, hoping to find out some answers. There's also a creepy little boy lurking about. "Pretty Little Liars" airs Monday nights at 8 p.m. ET/PT on ABC Family.
