Strongest claims in this topic
Cold reading explains mediumship
Stage mentalists reproduce 'mediumship' on demand. Cold and hot reading are well-documented techniques.
Consciousness is produced by the brain (materialism)
The materialist / physicalist view: lesions, drugs, anesthesia, and imaging all show tight brain–mind coupling, and physical mechanism explains an enormous range of phenomena. Why neural activity feels like anything at all remains the open exception.
Déjà vu
About two-thirds of adults report experiencing it. The neurological mechanisms are partly understood; the spiritual interpretations (past lives, glimpsing other timelines) are much larger claims.
Acquired savant syndrome
Peer-reviewed cases describe new, intense artistic or musical activity after brain injury, stroke, or dementia. They do not show a complete skill being magically installed without learning.
Cryptomnesia explains past-life memories
Cryptomnesia — recovering forgotten material as if new — is a real, well-replicated phenomenon. It explains many past-life cases.
The Mandela effect
Large groups remembering the same false detail (Berenstein vs Berenstain, monocled Monopoly Man) is real and follows the well-known mechanics of false memory. The 'parallel universes' reading is unsupported.
Weakest or most speculative claims
Boltzmann brains
In a long-lived, accelerating universe, random thermal fluctuations could spontaneously assemble a self-aware brain with false memories of a coherent life. Several modern cosmological models appear to predict such observers should statistically dominate — which is widely treated as a reason those models are wrong, not as evidence about you.
Shadow people are external entities
Most reports happen at sleep boundaries or in peripheral vision — exactly where the brain is most prone to producing humanoid silhouettes. The 'external entity' reading is a much larger claim.
Hypoxia and neurochemistry explain NDEs
Hypoxia, hypercarbia, REM intrusion, endogenous DMT, and ketamine models reproduce many NDE features. Veridical cases resist the model.
Acquired savant syndrome
Peer-reviewed cases describe new, intense artistic or musical activity after brain injury, stroke, or dementia. They do not show a complete skill being magically installed without learning.
Key verified sources
A strong neuroscience anchor for the brain-dependence side of the consciousness cluster, while still admitting unresolved problems.
Useful as a claimed replication/extension of the 2007 Windbridge-style protocol; still controversial, but much stronger than anecdotal stage mediumship.
Documents de novo artistic behavior after trauma but also shows why 'instant mastery' is misleading: onset was delayed and the observable skill evolved through sustained activity.
The clearest statement of how the Boltzmann-brain count is tamed by a finite vacuum lifetime; companion paper to 'Return of the Boltzmann brains'.
