Night of the Living Dummy III (1) - S2-E24
Character mistake: When Zane sees Rocky with the hockey mask, he seems legitimately terrified when he notices him. However, he was responsible for putting him there and no-one else was around. There is no reason for him to express real fear when he planned for his appearance the whole time. (00:11:44 - 00:12:08)
Suggested correction: He only pretended to be scared in order to fool his cousins, uncle and aunt.
Night of the Living Dummy III (2) - S2-E25
Revealing mistake: When all the dummies are set up in Zane's room, you can see in many shots that what is meant to be Zane as a dummy is a complete human.

The Ghost Next Door (1) - S4-E3
Deliberate mistake: Right before rising to check out who was calling her name, Hannah sets her laptop, which she was using to write a letter, on the bedspread. The computer screen is shown to be blank, meaning, 1. she switched it off, which she didn't, or 2. it was out of order, which doesn't make sense since she was using it seconds before. (00:02:10)
The Ghost Next Door (1) - S4-E3
Continuity mistake: In the scene where Hannah Fairchild enters Danny Anderson's house, in the close-up shot of her on the front steps before she enters, a huge gust of wind blows and messes up her hair, but in the close-up shot of her entering through the front door, her hair is visibly straight again. (00:15:25 - 00:27:30)
Continuity mistake: The size and shape of the stain on Nicholas' shirt after he falls into the spillage, changes.
