Imagine the exhibits experience their death again on the date they died. For example, Octavius died 19th August, and every year on that day/night he becomes very ill and loses a lot of blood, it looks like he is bleeding to death. Jed sits frustrated next to his bed and holds his hand the whole night.
Teddy experiences the pains of embolism on 6 January again, while Wea takes care of him.
Ahk can’t speak for the whole night and sounds like he is about to choke and throws up blood. Larry comforts him with songs and doesn’t leave his side till dawn.

The next night they just walk around like nothing happend.
