Extraphysical Monism is an extraphysicalist philosophy that both, physical and extraphysical are the same thing and the same substance, but on different levels of existence, where physics does not disprove extraphysics nor extraphysics disprove physics, where all physical and extraphysical are the same and that all physics and extraphysics are interconnected and there's no difference in the substance of physics and extraphysics, just different levels, states and forms of matter and physics. Extraphysical Monism is usually advocated by Atheist Extraphysicalism, since on atheist extraphysicalism both, physics and extraphysics are the same thing such as all physical and extraphysical life forms are the same and even that natural sciences and extranatural sciences are the same thing on different states and levels, and extraphysical monism is usually advocated by classical extraphysicalism itself since it usually considers everything as extraphysical.

Extraphysical Multiverse is a multiverse hypothesis where multiverses exist at extraphysical level and it's hard or almost impossible to detect them by physical mean. Extraphysical multiverse also stances that other universes and dimensions exist in a way it's only possible to access them by spiritual-extraphysical means or by technological-extraphysical means, and theoretically, they would have several defense mechanisms and/or properties in order to do not be detected by physical/natural means but only by spiritual and extraphysical means. Extraphysical multiverse theory is often used to explain phenomena like astral projection, near death experiences, out-of-body experiences and spiritual phenomena and experiences in general, together with physical-extraphysical entanglement of bodies, extraphysical mechanics, extraphysics and extraphysicalism.

Extraphysical Panpsychism is the view that mind or a mindlike aspect is a fundamental and ubiquitous feature of reality, where mind or that mindlike aspect exist at extraphysical level and extraphysics play an important role at physics and where all living beings and things actually have an extraphysical mind and an extraphysical counterpart as well. Extraphysical panpsychism seeks to unite the views of extraphysicalism and of panpsychism into single philosophy, and to develop a theory and a view that can describe the world and reality and physical level and extraphysical level where both, physical and extraphysical levels are part of the same reality and mind.

Extraphysical Placebo, also Extraphysical Placebo Effect, is an extraphysicalist and an extraphysical mechanics concept where the placebo effect is actually the influence of extraphysics and of the extraphysical mind and spirit over someone's physical body, such as the influence of the extraphysical level on someone's physical body. Extraphysical placebo is used to explain about how majority of the spiritual experiences are so similar to placebo effect and about how it's really hard to have a spiritual experience that could overcome the placebo effect as well. The term is also used for the development of extraphysical-based medicine and technology that could modify physical bodies and things only by extraphysics.

Extraphysical Relativity, also referred as Theory of Extraphysical Relativity, is an extraphysical theory that supports that one being or body will keep their same extraphysical properties in any extraphysical level or world, being subject of the extraphysical conditions of each level and world, but still keeping their same properties and laws in any other extraphysical world. Extraphysical relativity also supports that extraphysical properties of matter can also be kept at physical worlds and levels and they will still behave the same as if being on other extraphysical levels.

Extraphysical Spirit, also extraphysical soul, is a group of hypothesis proposing that classical mechanics and quantum mechanics cannot explain or proof the existence of the soul and the spirit, similar to what happens with extraphysical consciousness, but with souls and spirits. It posits that extraphysical-mechanical phenonema duch as extraphysical entanglement and extraphysical superposition, may play a important part in living beings and explain soul and spirit and even proof the existence of soul and spirit. The term is also expanded to refer to the idea of orchestrated extraphysical spirit, that's about the spirit/soul exists at extraphysical level extraphysical level and the manifestations at classical and quantum level are byproducts of the soul/spirit acting at extraphysical level, and that the extraphysical spirit and the extraphysical consciousness are one and the same.

Extraphysical theory is a term used to refer to extraphysical mechanics and its branches inside physics as a whole, extraphysical theory is mainly used by physicists to refer to extraphysical mechanics as a theory, similar to string theory. Since extraphysical theory and string theory are really similar to each other, even some physicists even consider extraphysical theory is a fundamental theory for string theory such as quantum theory is a fundamental theory for classical physics.
