These are the phenomena which occur at the time of death of a person.
An example that Peter Fenwick quotes is of a Julie Salmon who described being suddenly woken up and actually calling out “Mum” - It was 2am, so she refrained from calling the hospital, but she was later rung by the hospital at 7:30 in the morning confirming that her mother had indeed died at 2am”.
It’s the repeated uncanniness of the timings that constitute the evidence coupled with the pattern of alerting a loved one to a death. There are literally thousands of accounts like these.
To me this is common sense. If you suddenly found yourself the other side you’d want to do what you could to lessen their grief and just quickly say goodbye.
Often it’s the detail which is undeniable and where the death is unexpected, very convincing. An Elizabeth Daniel heard her ex-husband’s voice one morning at 4:15am in a way so clear it could have been in the room and knew that he had died. He said “We no longer need to talk about things”. She had divorced him and remarried 28 years previously. So it was a couple of days later before she found out that she was right.
“Many different areas of the person’s life seem to be interconnected at the time of death. Occasionally their animals behave strangely, their clocks may stop, bells may ring.. lights may switch on or off. All these aspects of the dying process fit neatly into a theory of consciousness in which the universe is highly interconnected and has love and light at its very core. They fit poorly with the current neuroscience idea that consciousness is generated by the brain and remains local to the brain”.
