This is why people have been mistakenly buried alive due to thinking "Unconsciousness different from sleep" = Death; a noteworthy example is Octavia Smith Hatcher who "died" due to a strange illness nobody knows anything about; she was buried and everyone went on living their lives as usual; less than a week after her burial the symptoms of her strange illness (coma) started showing amongst many of the townspeople except everyone that showed the symptom eventually regained their consciousness, seeing this Octavia's husband decided to exhume her grave thinking she might've been buried alive, he did only to find out his worst fears were true, The lining on the inside of the coffin had been scratched and torn to pieces. Octavia’s nails were bloodied and broken , and her face was contorted with horrific fear. She had woken up, suffered excruciating pain and died in the ground after being buried alive
