relating to a state of being or experience which encompasses mind, soul and body.
...with respect to each individual's psychobiotic needs
A state of being when something at the submolecular level sends a person off the deep end and they go schizo or nuts for no apparent reason. The base of biomolecular exchange might be due to viral or bacterial agents which imbalance the potasium or sodium levels to such a degree that an altered concious state of awareness makes a being out of control or under a different set of controls.
This state may extend itself to nano-technologies sooner than we think wherein individuals might eventually fall into some Matrix-like remote viewer set of controls.
That dude was definely experiencing some psychobiotic issues.
