insomnia

in·som·ni·a
habitual sleeplessness; inability to sleep
Or in Jonah's case, a one way ticket to a sinister experience in a cold void beyond his control.
There is no escaping it, there is no way out.
No one can hear your screams. No one can save you from this nightmare.
Just when you think it's over, when the sunlight starts to peak through the slits in the curtain, the hallucinations are waiting for you beyond the door.
Paranoia isn't over yet.
This night has yet to begin.
