Continuity mistake: When Weol-ju is asking Yeomradaewang to be reborn, after Weol-ju says "Yes, I'm sure about this", Yeomradaewang replies "All right" with her hands clasped. A wide shot of the room is then shown where her hands are at her side. (01:01:17)
Continuity mistake: When Weol-ju is holding Guibanjang after he is impaled, in the shot where she says "Please don't, you can't leave me", she has a couple fingers placed on his shoulder, but when the shot cuts, the fingers placed on his shoulder have disappeared. (00:42:16)
Continuity mistake: When Kang-bae is looking over the broken pieces of the pot after waking up, there is one broken piece, where the string that was wrapped around the pot is shown next to it. The broken piece rotates 180° between shots. (00:50:21)
Continuity mistake: When Kang-bae is walking along the street the morning after Weol-ju disappears into the spiral staircase, there is a shot from behind him where a man far ahead of him can be seen walking past a mirrored lamp post. It then cuts to an angle much further behind Kang-bae, where the mirrored lamp post can still be seen, but the man walking past it has suddenly vanished. (00:52:10)
Continuity mistake: Guibanjang is walking along a sidewalk on a bridge and sees a man who he thinks about to jump. On the road beside him, on the lane closest to him, a black car can be seen driving past just as the shot ends. When the shot cuts, it is now a grey car. (00:12:41)
Continuity mistake: After Yeo-rin has struck one of the spirits over the head with a plank of wood, she turns around and extends her arms to stop the other spirits from coming toward her.

Continuity mistake: When Yeo-rin walks into the pop-up bar and sees Weol-ju lying on the floor, when the camera pans down to the floor, for a split-second, a knife can be seen next to Weol-ju. When the shot cuts, the knife has suddenly rotated more to the left. (00:33:12)
