Our reading
An editorial interpretation.
The speaker asks whether the listener remembers a demon that nearly escaped on the night the speaker died. The question treats an eerie, dramatic near-disaster as a shared memory, casually raising both the speaker's death and the creature's almost-breakout as things both of them once lived through.
