It's worth checking if you've accidentally remapped the controls before trying this, since you may have set it to a different button without knowing it. Lightburn is a mechanic unique to The Spirit World and exclusively afflicts those that interact with the latter, making them vulnerable to the light of Flashlights while using their Power. PC players simply need to tap the R button to drop a survivor. This interaction is painful to The Nurse, causing her to scream with each Blink. Since she does not entirely enter it, The Spirit World does not grant her the Undetectable Status Effect, but rather makes her appearance blurry and shimmery while blinking. Unlike The Wraith, who walks The Spirit World, The Nurse uses Spencer's Last Breath to pierce and quickly move through it. The Spirit World enhances his abilities, depending on the Add-ons he uses, and cloaks him from Survivors by granting him the Undetectable Status Effect. The Wraith uses his ancient Wailing Bell to cloak himself, which allows him to access and walk The Spirit World at increased Movement speed. Survivors have no means to enter it or interact with it.

This is evidenced by the fact that The Wraith minimally uncloaks himself each time he interacts with Props when cloaked. Notably, Killers within the Spirit World cannot interact with Survivors and objects outside of it. Its appearance is identical to the Entity's Realm, but those who traverse it see black fog covering their peripheral vision. The Spirit World is on a different plane of existence to the Entity's Realm. The Spirit World is used by The Wraith and The Nurse, other Killers do not have access to it.
