If you loved Doctor Sleep, try Before I Wake
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Mike Flanagan, and they both carry the dread, gut punch mood tags, and they sit in Fantasy / Horror territory. If that's the register that drew you to Doctor Sleep, the second film will land in a comparable space — through a different lens.

What Before I Wake is
Farm country. Late fall. A child’s drawing on the bureau. Bereaved couple takes in a sweet foster kid whose dreams become reality, and whose nightmares are even worse. Flanagan's sentimentality is a feature, not a bug.
