The age-old question of what happens after death has perplexed many, leading to a multitude of beliefs and opinions. Some, however, may have a more profound understanding of the afterlife, having personally experienced it.

It's not uncommon to hear stories of individuals who, despite being declared dead during medical procedures, return to life and share surreal accounts of what they witnessed.

Tina Hines belongs to this exceptional group. In February 2018, she suffered a cardiac arrest, and despite her husband Brian's valiant attempts to revive her, she passed away. During her journey to the hospital, Tina's life was restored six times by medical professionals, resulting in her experiencing a total of 27 minutes of death.

However, after being intubated at the hospital, she eventually regained consciousness and urgently requested a pen and paper to jot down an ominous message for her family.

In barely legible handwriting, Tina scrawled the words 'it's real.' When questioned about what was real, she simply nodded upwards.

"It was so real, the colors were so vibrant," Tina conveyed to AZfamily.com.

She explained that she saw a figure whom she believed to be Jesus.

Remarkably, experiences like Tina's aren't uncommon.

According to studies, while most people have no recollection of the period when they were technically deceased, around 10 to 20 percent report some form of visual or sensory occurrences during that time.

And though these occurrences may appear mystical, scientists have been edging closer to uncovering the truth behind what happens during near-death experiences.

In 2013, researchers at the University of Michigan conducted a study involving rats.

As per reports, there is a surge of brain activity just prior to death that surpasses that of the most alert, conscious state.

The leader of the study, Dr. Jimo Borjigin from the University of Michigan, commented, "A lot of people thought that the brain after clinical death was inactive or hypoactive, with less activity than the waking state, and we show that is definitely not the case.

"If anything, it is much more active during the dying process than even the waking state."

During the study, nine rats were monitored as they were approaching death. In the 30-second period after their hearts stopped beating, researchers observed a significant spike in high-frequency brainwaves.

Could Tina's experience simply have been a result of a surge in high-frequency brainwaves? We may never have a definitive answer.
