Psychic energy is an all pervasive energy or force (hence George Lucas' 'force' in Star Wars) that modern science has failed to discover and thus chosen to take a negative, skeptical stance upon it's existence. Thus anyone who claims to believe in the reality of psychic energy or the paranormal in general is deemed a superstitious 'kook'. The standardized and accepted definition of psychic energy is that of the biochemical energy essence of internal psychological thought and emotion whether as a part of the conscious or unconscious mind equivalent to Freud's concept of libido. The metaphyscial and/or paranormal definition generally views psychic energy in part as the above definition suggests in being physically interactive but is not itself inherently dependent upon the physical for it's sustenenance and/or existence. Thus a being of 'spirit,' a soul, i.e. a psychic energy life-form would have no problems with life-after-death since it was merely the physical body that died and not the actual being.

Psychic energy is generally conceived of as an all-pervasive essence which is not only the quintessential life-force but is also the medium or essence of force for all paranormal phenomena as well. People seem to have less problems with the concept of a psychic energy life-form whether angelic, demonic, or somewhere in between in characterization being the source of paranormal phenomena than they do with the idea that all physical beings are in truth psychic energy life-forms incarnate.

While science has yet to capture in a net and place in a jar a sample of psychic energy so that it can finally feel secure in venturing forth even so much the theory of it's reality, we 'lay people' can still speculate, experiment, and venture our own theories about what it is and how it work.

In general it is best to seek a more mundane probability of cause(s) for an unexplained event before jumping to conclusions about it being a paranormal phenomenon. In most cases such causes can be found. However, that does not preclude the reality of both psychic energy and the paranormal.

Psychic interactions and Biophysical interactions. The synaptic conduction of biochemicals (e.g. acetylcholine - ACh) in the central nervous system (c.n.s.) occur at the quantum level. This has lead many quantum theorists including both physicists and metaphysicists to speculate that the interaction of psychic energy with the physical body begins at this level within the central nervous system. Certain paranormal and/or mystical experiences such as kundalini or chakra (i.e. energy center) awakenings where the agitation or stimilation of the c.n.s. especially along the spine (i.e. the primary path or center of the c.n.s.) is a commonly associated albeit secondary symptom also suggest a psycho-physical connection
