SLEEP PARALYSIS HALLUCINATIONS FALL INTO THREE KINDS
Many Episodes Come With Something Seen Heard Or Felt
Those Experiences Sound Too Varied To Have Any Pattern
Researchers Sorted Them Into A Small Number Of Kinds
The Same Kinds Appear Across Different Samples
Statistical Analysis Showed Which Sensations Occur Together
A Research Team Built That Framework In The Late Nineties
The Link Between Those Kinds And The Brain Is Still A Hypothesis
Later Work Tested The Same Kinds More Than Once

THE INTRUDER FACTOR 👤
Sleep Paralysis Hallucinations Fall Into Three Named Kinds
Cheyne Rueffer And Newby Clark Built That Framework In 1999
They Tested It Against Several Large Samples
A Prospective Study Later Collected Reports From 383 People
Each Person Described A Single Episode Online
That Study Found Further Evidence For The Same Three Kinds
The First Kind Is Named Intruder
It Groups A Sensed Presence Fear And Hallucinations Together
Those Hallucinations Can Be Visual Or Auditory
What People Perceive Is An External Agent
A Web Study Of 279 People Measured Where Hallucinations Seemed To Be
Intruder Hallucinations Usually Seemed To Be Within A Meter
Cheyne's Team Proposed That Intruder Comes From A Hypervigilant State
They Suggested That State Begins In The Midbrain
Later Papers Call It A Threat Activated Vigilance System
The Prospective Study Tested Whether The Presence Is Central
Its Results Were Generally Consistent With That Idea
The Presence Largely Explained How The Sights And Sounds Were Linked

THE INCUBUS FACTOR 🫁
The Second Kind In The Framework Is Named Incubus
It Groups Chest Pressure Breathing Difficulty And Pain
Reviewers De Sa And Mota Rolim Describe It As Chest Pressure
Their Review Adds Shortness Of Breath
Incubus Is Also An Old Word For A Demon Blamed For Nightmares
That Word Is Recorded In English From About 1200
Its Latin Root Means One Who Lies Down On The Sleeper
Cheyne's Team Attributed Incubus To Hyperpolarised Motoneurons
They Tied That Effect To How Breathing Is Perceived
A Separate Review Notes Motor Neurons Are Inhibited During REM
That Inhibition Reduces Activity In The Muscles Used To Breathe
The Review Says This Could Account For Incubus
Incubus And Intruder Share One Feature In Cheyne's Paper
Both Imply An Alien Other
That Matches Occult Narratives Found In Many Cultures
The Same Web Study Also Measured Pressure Choking And Pain
It Classed Them With Touch As Contact Hallucinations
A Nearer Intruder Went With More Contact Hallucinations

UNUSUAL BODILY EXPERIENCES 🎈
The Third Kind In The Framework Is Named Unusual Bodily Experiences
It Groups Floating Flying Out Of Body Experiences And Bliss
De Sa And Mota Rolim Include Hovering Sensations In This Kind
In Out Of Body Experiences People See Their Own Body From Outside
Cheyne's Team Linked This Kind To Body Position And Movement
Later Papers Call This Kind Vestibular Motor Hallucinations
That Label Also Covers Illusory Movement Of The Body
In The Web Study They Often Seemed Beyond The Immediate Surroundings
Greater Distance Went With More Vivid Vestibular Motor Hallucinations
A Later Paper By Cheyne And Girard Called It A Distinct Factor
That Paper Drew On Self Reports From Two Online Surveys
The Findings Fit A Hypothesis About Out Of Body Experiences
Under That Hypothesis Normal Binding Of Bodily Sensations Breaks Down
Vestibular And Motor Sensations Contributed To Them Fairly Separately
A Study Of 5799 People Examined All Three Kinds Together
It Compared Novices With Frequent Experiencers
The Three Kinds Looked Highly Similar For All Groups
Novices Separated The Three Kinds More Clearly In Their Reports
The Authors Suggest Frequent Experiencers Conflate Separate Episodes
They Say The Pattern Likely Comes From Brain Activity During REM Sleep
