Maybe Emma's dreaming or simply trapped somewhere weird. Noone else appears to be in an AU. There's an Emma flashback (I assume via clothing) and the rest of the season resumes as normal.

There's the previous episode with EQ, Regina, Robin and Stealthy, but perhaps it's some wish or major magic mojo that EQ conjures gone awry and/or the dead make a temporary visit of some sort. Then this episode is Emma facing her villain but ends in some weird state of fate. (And/or Regina is dead in a weird world as are the dwarves, lol).
