Interdimensional beings
Interdimensional beings are entities that exist in or move between different densities or dimensions of reality, distinct from conventional extraterrestrials (who originate from other planets within a single density). Some interdimensional beings are native to higher densities who visit lower-density physical reality; others are entities from parallel dimensional planes that intersect with physical space.
Conceptual distinction from extraterrestrials
The Galactic Federation of Worlds' cosmology distinguishes between beings from other planets within the same density (extraterrestrials proper) and beings that move between densities or originate from other dimensional configurations. The Zenae use "etheric and interdimensional travel as well as time travel," placing them in the interdimensional category despite originating from a physical star system.
The Anunnaki and dimensional portals
The Anunnaki's home planet Nibiru exists in a "parallel dimension"; their portal into the material galaxy is located in the Orion zone. This makes them technically interdimensional rather than purely extraterrestrial — originating from a different dimensional plane rather than a different planet within the same physical universe.
The Orion nebula portal
A singularity within the M42 nebula in Orion functions as an interdimensional portal — not a black hole, but a "doorway" between dimensional planes that has made the Orion zone strategically critical and bitterly contested between the Ciakahrr Empire and the Orion Alliance.
Density-jumping species
The Arcturians (Ohorai) exist primarily at 7th–9th densities but can choose to manifest in 3rd-density physical form. They are quintessential interdimensional beings: native to a high density, voluntary visitors to lower ones. The Giansar of Sigma Draconis are described as "a dimension-hopping sorcerer or priest class among the reptiloid species," specialists in crossing between dimensional planes through dark-ritual techniques.
The Akart interdimensional method
The Akart (Sextans constellation) possess an unusual interdimensional travel method that allows them to transfer their light-being and incarnated body between dimensions without the ability to simultaneously transport external objects — meaning their clothing cannot accompany them.
The Ciakahrr dimensional lockout
The Galactic Federation of Worlds has locked the Terra-based Draconians into the 3rd-dimensional plane, and separately blocked off-world Draconian reinforcements from penetrating the Terran solar system via an energy barrier at the system's outskirts.
Government contact with interdimensional entities
Jacques Vallée disclosed in 2025 that credible sources had informed him of ongoing structured communication programs between government specialists and non-human entities at classified facilities. Vallée described these entities as potentially "the controllers... the higher level entity," suggesting a tier of intelligence above the beings typically encountered in physical craft or field encounters. He characterized the interaction as sophisticated and complex — consistent with the hypothesis that the communicating entities are not extraterrestrial in the conventional sense but operate at a level that makes standard ETH categories inadequate.
Jinn and folkloric parallels
The interdimensional being category overlaps with multiple Terran folkloric traditions. The Giansar's "dimension-hopping" and dark ritual practices correspond closely to descriptions of the Arabic/Islamic concept of Jinn, and the Telosii — vibrating in "a slightly higher density" from their underground habitats — correspond to traditions of hidden people, sidhe, or the "shining ones" in Celtic mythology.
Sasquatch
Sasquatch is classified within this wiki as an interdimensional being, reportedly capable of dimensional phase-shifting, explaining both their physical encounters with humans and their apparent disappearances.
