Nightmare on Nightmare Street by R. L. Stine

From the master of spine-tingling horror for young audiences, A Nightmare on Nightmare Street is full of strange sounds, terrifying visions, and things that go bump in the night.

Twelve-year-old Joe Ferber, his sister Sadie, and their parents have just moved into a house that has all the hallmarks of a horror movie--tombstones in the basement, a creepy doll lying around, strange noises in the wall, and so on. As Joe tries to fall asleep on the first night, his nightlight begins to flash and change colors, and the creepy doll appears in his bed ... and then twelve-year-old Shawn Hannigan wakes up from a dream.

Shawn and his little sister, Addie, are seemingly living in the same house with their mother. But when they arrive at their new school for the first day, the teachers are all wearing animal masks, and the principal's office is pitch black and full of noises. At the end of the day, a stranger claiming to be Shawn's mom picks him up and tells him he doesn't have a sister ...

As more and more strange things happen to each of them, Shawn and Joe have to figure out what is real, and what is a nightmare ...
