What happens if you faint and nobody wakes you up?
It’s possible to lose consciousness only temporarily and then wake up. When this happens, you think you’ve simply fainted.

Like shock, losing consciousness due to alcohol is not technically considered fainting, but it may or may not be cause for concern.
What happens to your body when you lose consciousness?
As the brain stops getting enough blood flow to stay conscious, it stops sending out signals to the muscle cells. The muscles lose their tone and the body just collapses into whatever heap gravity pulls it to. Occasionally, that sudden exit of blood from the brain leads to a little nervous impulse—kind of like static through a phone line.
Can the brain find its way back to consciousness?
Both general anesthesia and coma are major perturbations to brain’s normal activity, and in some cases, the brain cannot find its way back to consciousness. “Some people, after injury, will remain in some minimally conscious state forever, but some people can recover years after the injury,” Proekt said.
Are near-death experiences a return to consciousness?
This anecdotal evidence demonstrates that the near-death experience is a return to consciousness at the point of death, when the brain is dying. Dr. Melvin Morse thoroughly researched Olga’s testimony and every detail had objective verification including the scribbled note by the son-in-law.” [1]
