She's ba-ack. Well, at least in another dream sequence.

In this sneak peek of Pretty Little Liars Season 2, Episode 24: “If These Dolls Could Talk,” Alison (Sasha Pieterse) once again shows up to drop some cryptic musing on a Liar, as she did with Hanna (Ashley Benson) in the hospital and Emily (Shay Mitchell) in the barn. This time, Spencer's (Troian Bellisario) the "lucky" recipient of this weird, other-worldly apparition.

Just like with Alison's other bizarre appearances, we have to assume this is a dream/hallucination. Even if she's just a figment of Spencer's subconscious, this dead girl seems to have a useful clue or two in mind. If only she'd explain what she means instead of talking in riddles...

Be sure to tune in for the next episode of Pretty Little Liars on Monday, March 12 at 8 p.m. ET/PT on ABC Family.
