The period shortly after death seems to be a strange thing. During this time, the body has undergone various changes, from being alive to being completely dead. Although some of these changes (such as hardening and discoloration) can be seen in crime TV shows, other changes seem far-fetched for the human body.
Nonetheless, what the corpse can do is shocking and creepy. From the birth of the awareness of death, the changes in the body after death are almost unrealistic and impossible to achieve. The following list is not suitable for the faint-hearted or those with stomach problems.
There are countless stories of those who have come back from near-death experiences and have given their interpretation of what they believe the afterlife is like. While many are left to wonder what happens after we die, scientists may have at least part of an answer.
Scientists have found that after death, the brain can retain some semblance of awareness. This means that after one has passed, they might actually be aware they’re dead. In a study of 2,060 cardiac arrest survivors who had been declared legally dead, meaning that they no longer had identifiable brain function, around 40 percent claimed they were still aware of their surroundings and conversations going on around them.
The period doesn’t seem to last long, research has found. As death is a process, the time between oxygen leaving the system and the brain sending its last signals can leave room for awareness. Scientists believe that there is an average time of 10–20 seconds of awareness after death. A severed head, for example, still produces EEG waves even after death, though a portion of these seconds have lead scientists to believe the brain enters a stage of unconsciousness.
Still, the idea that a body may be aware that it’s dead is nothing short of unsettling.
