Summary
In Hollow Knight, Essence is an ethereal substance that forms and exists as fragmented light and the dreams, memories , and thoughts of bugs. Additionally, Essence comprises various beings found throughout Hallownest and the Dream Realm, and even comprising the Dream Realm itself. These beings can manifest as Spirits or bugs within the Dream Realm.

Uses
Being comprised of Essence grants a minor array of abilities, namely:


 * Inorganic Physiology and Light Manipulation (Type 1. Essence is fragmented light.)


 * Non-Physical Interaction and Extrasensory Perception (Can see and interact with Essence.)


 * Invisibility, Intangibility, and Incorporeality (Essence beings cannot be seen or interacted with without the Dream Nail. Essence beings are collections of Essence particles taking the forms of bugs and a number of Essence beings exist within the Dream Realm; a place made of Essence that makes up dreams, memories and thoughts.)


 * Immortality (Types 1 and 7. Dreams are endless, and Spirits remain in the state they take without aging. The Dream versions of waking bosses are eternally in their idealized state. Spirits are the lingering memories of bugs.)


 * Abstract Existence and Limited Memory Manipulation (Type 1. Essence makes up memories, thoughts, regrets, and dreams, including the Dream Realm as a whole. The Spirits in the Spirits' Glade being destroyed by The Knight causes Revek to lose his memories of them. )

Limitations
Weaker Spirits cannot tangibly interact with the material world, and they can be split into Essence particles by powerful enough Dream Manipulation. For stronger Spirits, this can only occur if the Spirit is exhausted and/or gives up. Most beings in the Dream Realm cannot appear in or interact with the waking world in any way, and their dreams need to be entered in order to be encountered.
