In my mind, there are really four things that it could mean:
1. The zombie apocalypse is upon us and its time to start hunkering down.
2. Some higher power granted the parents a chance to hear their boy one last time. Though it is more creepy than anything, the choice of words are moderately comical...
3. The boy wasn't really dead to begin with because his vitals were suppressed by some drug that may or may not have tricked his body into shutting down after he woke up.
4. The whole thing is a lie to gain attention. This wouldn't be as much fun as the other options...
Regardless, it is definitely a creepy story.
