Distinctions	Exist as avatars of lifeforms within material reality. Lifeforms may give up their forms and permanently become Oneiroi, or continue to exist within the Oneirosphere after death if connected to an Egregore. While many are independent consciousnesses, a majority are constituent consciousnesses of Egregore collectives. Appearance is largely customizable, aside from within certain Egregores.
Average Lifespan	Immortal, although the lifeform they are the avatar of can be killed.
Abilities	Manipulation of proximate reality. Shapeshifting. Astral Projection.

Endangered	Least Concern
Sociocultural Characteristics
Intelligence	Sapient, Sentient
Habitat	Dreams

The Oneiroi are a type of intelligent thoughtform entities which biological lifeforms connected to the Oneirosphere become during sleep (simultaneously giving the reality the form necessary for it to exist), functioning akin to avatars which can be used interact with their own and other people's subconscious worlds during sleep. Not everyone is able to clearly perceive and remember experiences in the Oneirosphere, often forgetting or misinterpreting the Dream Entities and Visitors they met in their dream, especially if their dreams are especially incoherent. There are two main types of Oneiroi, 'Corporeal Oneroi' and 'Non-Corporeal Oneiroi', which are either constituent consciousnesses of an Egregore or 'Transitories' which visit other dreamscapes without a mental link. Appearance-wise, Oneiroi vary wildly as they are able to shapeshift to some degree in order to assume a form of their own design, with the default unmodified form most being a shadowy replica of their (former or current) corporeal body, though of course in Egregores with more cohesive/integrated structures the forms of the constituent Oneiroi tend to fairly uniform

"Corporeal Oneiroi" are living beings in Corporeal Reality that can interact-with and enter the Oneirosphere during sleep. Because of their background as living beings that simply 'connect' with the Oneirosphere, they tend to have significantly more limitations and disadvantages within the Oneirosphere than 'Non-Corporeals'. 'Dying' before waking up (experiences in one's own dreamscape tend to 'automatically' do this, but is much less reliable on other dreamscapes) is very dangerous for Corporeals, generally causing their subconscious to either be destroyed or subsumed into the neural network of the dreamscape they have connected to, being the basis of involuntary Egregore expansion.

"Non-Corporeal Oneiroi" are individuals who have abandoned their physical bodies and fully migrated to the Oneirosphere, giving up their lives in return for unconscious immortality. They lack their own individual dreamscapes, instead primarily traveling through other people's dreamscapes (thus they are much more common within Egregores than Corporeals). They are able to traverse through Dreamscapes much easier than Corporeals, and are incapable of dying thanks to no longer being tethered to a body.

If they are skilled enough, Oneiroi can travel from their own Dreamscape to other people's Dreamscapes based on either physical proximity in corporeal from which they are able to travel further by using said people as 'relay points' reality or through connecting to an Egregore (which act like easily navigable chains of relays), connecting their own subconscious with whichever Dreamscape they enter in order to enter it. A notable portion of Oneiroi never learn how to accomplish this, instead never leaving their own Dreamscape. Due to their similar propeties, Oneiroi are capable of entering nearby Memoria Spaces as if they were ordinary Dreamscapes despite being tethered to reality and lacking a single 'Host mind'.
