Also consider how many human beings have existed on this planet over the last 100,000 years - the length of time that humans as a separate species have been estimated to have been in existence. That many people, that many souls, there'd be so many "ghosts" on the planet, from cavemen to ancient Babylonians to Romans to Normans to Mandarin Chinese to Napoleonics to Zulu warriors to Russian freedom fighters to German Nazis to modern day soldiers to the civilian populations of every culture on Earth that has ever existed. You wouldn't be able to sleep, drive, eat, go to the bathroom, etc. without ghosts watching you (assuming they could see).

Godless Gazoo say: It means they have an over active imagination. Or more likely....they are just lying.

elj2017c say: Dead people cannot come back to life on their own. But there are unseen demons. The demons show a similarly evil disposition. In Jesus’ day, they robbed people of their speech and sight. They caused a man to slash himself with stones. They dashed a boy to the ground and “violently convulsed him.”—Luke 9:42; Matthew 9:32, 33; 12:22; Mark 5:5. Reports from around the world show that Satan and the demons are as malicious as ever. Some people they strike with illness. Others they harass by robbing them of sleep or by giving them terrible dreams or by abusing them sexually. Still others they have driven to insanity, murder, or suicide.
(Ecclesiastes 9:5) "For the living know that they will die, but the dead know nothing at all, nor do they have any more reward, because all memory of them is forgotten."

mark say: The head often decays much earlier than the rest of the ghost. The heads fade away, so the older ghosts seem to be headless.
