Some Believe This Ability To Be :
- Chi - The circulating life force whose existence and properties are the basis of much Chinese philosophy and medicine
- Electrokinesis - The kinetic ability to conjure & manipulate varying amounts of electricity with your mind and / or body alone
- Vasoconstriction - The constriction of blood vessels, which increases blood pressure
- Nerve Blocking - Blocking nerve receptors with the mind
- Sensory Amplification - Amplifying nerves sensitivity
- Chemical Control - Control over chemical releases by brain to affect body parts
- Muscle Straining - Flexing all muscles in the area of effect
- ASMR - Autonomous sensory meridian response, people whom have ASMR have this feeling through different triggers and stimuli but a less common intentional attentional control is possible which would be what this is. This could also be linked to a type of synesthesia.
So these theories basically are guesses from a theological, spiritual, psychical, medical or logical viewpoint.
