As they start to sum up The Haven-Slocum Theory, the couple quotes from Johanne Scefing's posthumously published journal:
At this late hour I'm unable to put aside thoughts of God's great sleeper whose history filled my imagination and dreams when I was a boy. I cannot recall how many times I read and re-read the story of Jonah, and now as I dwell on Navidson's decision to return to the house alone I turn to my Bible and find among those thin pages these lines:
So they took up Jonah, and cast him forth into the sea: and the sea ceased from her raging.

(Jonah 1: 15) [185]

It seems a somewhat bizarre reference, until Haven and Slocum produce a second PEER table documenting what happened once Navidson entered the house on Ash Tree Lane:
POST-EXPOSURE EFFECTS RATING

Brookes: improved sleeping. 1: Sheriff Axnard: end of nausea. 2: Billy Reston: decreased sensation of cold. 3: Daisy: end of fever; arms healing; occasional echolalia. 1: Kirby "Wax" Hook: return of energy and potency. 4: Chad: better goal-directed flow of ideas and logical sequences; decreased aggression and wandering. 1: Karen Green: improved sleeping; no more unmotivated

Even more peculiar, the house became a house again.
As Reston discovered, the space between the master bedroom and the children's bedroom had vanished. Karen's bookshelves were once again flush with the walls. And the hallway in the living room now resembled a shallow closet. Its walls were even white. The sea, it seemed, had quieted.
" Was Navidson like Jonah?" The Haven-Slocum Theory asks." Did he understand the house would calm if he entered it, just as Jonah understood the waters would calm if he were thrown into them?"
Perhaps strangest of all, the consequences of Navidson's journey are still being felt today. In what remains the most controversial aspect of The Haven-Slocum Theory, the concluding paragraphs claim that people not even directly associated with the events on Ash Tree Lane have been affected. The Theory, however, is careful to distinguish between those who have merely seen The Navidson Record and those who have read and written, in some cases extensively, about the film.
Apparently, the former group shows very little evidence of any sort of emotional or mental change:" At most, temporary." While the latter group seems to have been more radically influenced: "As evidence continues to come in, it appears that a portion of those who have not only meditated on the house's perfectly dark and empty corridors but articulated how its pathways have murmured within them have discovered a decrease in their own anxieties. People suffering anything from sleep disturbances to sexual dysfunction to poor rapport with others seem to have enjoyed some improvement." [186]
However, The Haven-Slocum Theory also points out that this course is not without risk. An even greater number of people dwelling on The Navidson Record have shown an increase in obsessiveness, insomnia, and incoherence: "Most of those who chose to abandon their interest soon recovered. A few, however, required counseling and in some instances medication and hospitalization. Three cases resulted in suicide."
