Some conjectures about the mechanism of poltergeist phenomenon
  Poltergeist accounts concern at least four kinds of strange spontaneous manifestations, such as burning of materials, failures of electric equipments, rapping noises and movements of objects. A simple analysis of phenomenology of these disturbances shows that they might have a common origin, that is, a reduction in strength of molecular bonds due to an enhancement in polarization of vacuum which decreases the actual electron charge. Arguments based on Prigogine' nonequilibrium thermodynamics are proposed, which show how transformations in brain of some pubescent childs or young womans might be the cause of these effects.
