Sometimes dead does not mean gone.

In post–War England, a writer and sometime-ghost hunter investigates a reported haunting at a boys boarding school.
In The Awakening, consciousness is carried by the dead — a plane of “haunted boarding school”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing grief, memory, trauma, belief, isolation.
Films fighting at the same level of reality, about the same things.
