Nightmare Fuel / Be Careful What You Wish For

The book contains examples of:

• The sequence where Samantha accidentally erases everyone else from existence is quite chilling. That chapter does a pretty good job of conveying what it would actually feel like to be the only person in the world. She's scared out of her mind from the total isolation, and starts to panic about how she can't take care of herself and has no idea what she's supposed to do now, and nearly breaks down crying before she manages to find Clarissa and undo the wish.
• When Samantha wishes that Judith was her friend, both the book and the episode portray her as a creepy stalker-type, who at one point breaks into Samantha's home in the middle of the night.

• The sheer scope of Clarissa's power warrants a mention. She at first appears just a simple witch, but as the book progresses she appears to be something even more powerful and alien. Through "simple" wish granting, Clarissa shows she can blink humanity out of existence, inflict disease and sickness, alter your personality, turn back the flow of time, and transform people into animals. Just what else is she capable of? One should be grateful she's one of the "nicer" magical beings in this series.

The episode contains examples of:

• In the episode, rather than wishing for everyone to disappear like in the book, Samantha instead wishes they would "buzz off". Clarissa makes this true, all right... by turning everyone into flies. Especially disturbing for anyone with muscaphobia. Also, Judith's wish that she'd be admired by all who see her causes her to turn to stone. Leaving Judith in a possible And I Must Scream situation. And the single crow that lands on top of her head.
