Abstract in brief

  • The text discusses sleep paralysis (SP) and its associated hallucinations—called hypnagogic and hypnopompic experiences (HHEs)—which often resemble supernatural or paranormal phenomena and are similar across different cultures and times, aligning with how REM sleep functions neurologically.
  • A structural model is proposed that explains these experiences through three factors: Intruder (sense of presence, fear, hallucinations originating from hypervigilance in the midbrain), Incubus (chest pressure, pain, breathing difficulties linked to motor neuron hyperpolarization), and Unusual Bodily Experiences (floating, out-of-body feelings, and bliss, related to conflicts in body orientation and movement).
  • These factors suggest that many hallucinations during sleep paralysis relate to perceptions of an alien presence and physical sensations that challenge typical bodily and self-awareness, providing insights into how brain states and cultural narratives shape these supernatural experiences.]

@DrMMGilchrist1 @Otto_English @UtterBolloxPod Are vivid visual, auditory, tactile, or even kinetic perceptions. Ex: a sensation of impending threat, feelings of suffocation, or sensation of floating - are often cited as sources of accounts of supernatural nocturnal events and paranormal experiences. https://t.co/jMJEIi9iiV
