Usually described as floating over your body, calmly observing ourselves from above, implying that our sense of self need not be subjectively locked into our body.
Out-Of-Body experiences (OBEs)
Replicability of OBEs
There is no good evidence that people are truly floating above their bodies during OBEs
Falsifiability of OBEs
Our brain has the ability to be disrupted, and creat a similar effect that makes us believe were having an OBE. Certain drugs replicate that as well, such as Ketamine (Special K)
Reported by people who’ve nearly died or thought they were going to die
Near-Death Experience (NDEs)
During Near-Death Experiences (NDEs), What is something many people who’ve experienced one claim to have seen?
Often during NDEs when a patient suffers from one and claims to have seen the afterlife , it is culturally driven.
Falsifiability of Near-Death Experiences
the evidence is insufficient to support the extraordinary claim that we get ushered into an afterlife during NDEs
Déjà vu
Feeling of reliving an experience that’s new
