Corrected entry: When Nancy is taking a bath and Freddy's claw appears in the tub with her. When they first show her in the tub, she is covered in bubbles and the water is full of bubbles. When the claw reaches up between her legs, there are hardly any bubbles. When she wakes up (only a few seconds later), the bubbles are covering her and the water again.

Correction: As you said. "When she wakes up. " When the claw reaches up between her legs, this is part of the dream as Freddy was not in the real world yet. Therefore things changing in a dream are not a mistake.
