On the time of loss of life, it is also tough for scientists to interview caregivers about any lucid moments that can have happened.
Explanations for terminal lucidity lengthen past science. Those moments of psychological readability is also some way for the demise individual to mention ultimate goodbyes, achieve closure earlier than loss of life, and reconnect with friends and family.
