I have no clue what book this was from - some assortment of scary stories I read as a kid. But one story in it like, deeply traumatized me, pretty much for life lol.

It's about a kid who moved to a new house with family - iirc, the last family there had died, but he didn't know that?

Anyway, he was never scared of the dark before, but became scared of that dark in that house, which baffled his parents. He started sleeping with a nightlight and light on, and he could see and sense this darker-than-dark patch of pulsating deep shadow in the furthest, least lit corners of his room.

One night he wakes up in terror to see his lights are out. He runs downstairs to his parents room and they tell him there's a power outage, everything will be fine, but he can sleep with them if he's scared. He goes to sleep between them, still terrified.

He wakes up again a little later in the house, when everything is still dark for the night. To his horror, he realizes that both of his parents are dead, and he can feel the inky blackness in the room getting closer and closer to him.

That's it, like, damn. As a kid that got me bad. If anyone remembers this book please share?
