Do you believe in ghosts??
(multiple choise allowed)
Are there ghosts?
In describing someone dying, the Bible says "They gave up the ghost." This means their spiritual soul left their physical body. So technically anyone without a physical body is a ghost/spirit/soul. So in that way, of course ghosts exist. Maybe you meant to be more specific- like "Do ghosts roam the earth."
There have been only three (who appeared, not roamed)- all of whom were godly, not scary- Samuel, Moses, & Elijah, unless you consider Christ a ghost- that would mean seeing Him without His physical body- like on the mount of transfiguration.
When people think of ghosts, they tend to think of souls who were evil when alive, and now roam through the earth causing havoc and fear. This is simply not so. God is in control of all things- therefore ghosts would need to be allowed to roam the earth after death.
The devil was cast down to the earth (physicality) as punishment. He and demons must be in something physical at all times (possibly even a germ). So even they cannot roam the earth freely as a floating spirit. Likewise, such as in the story of the rich man and Lazarus, the rich man could not escape his torment to come back to the earth, or go anywhere else. He even requested to Abraham for someone from the dead to go back to the earth to warn his brothers of the place of torment, he was denied. So if someone today is convinced of a ghost, it is either mental illness, or giving in to a tempting thought- which happens by suppressing truth.
Are there still demon possesed?
My answer is in the "Are there mummies" paragraph...
Are there mummies?
When Christ raised Lazarus from the dead, He said to unwrap him / take off his grave clothes. So technically I guess you could say he was a mummy. Not only he, but Christ raised many from the dead- who could have been dressed like mummies we see in movies today. After Christ and the apostles were gone, and God's Word was complete, miracles ceased (we still have the power of prayer). So no longer do the dead get raised (until Christ returns), no longer are there people who are demon possessed (there is no longer a prophet, Christ, or one of the 12 apostles to cast them out, although through germs, temptation, and mental illness a person can act like they are, but since the demon would not have the 'steering wheel' so-to-speak, they wouldn't be able to do supernatural things such as climbing walls- the person still has complete control over their own body- so it is the same as anyone who listens to a demon (temptation).
Are there zombies?
The Bible speaks of a place between two hills, possibly a graveyard, where dead, decaying bodies were possessed by demons, and people were afraid to pass through there. So technically you could say they
were zombies. But again, like I said in the mummy paragraph, that doesn't happen anymore, nor will it again before Christ's return.
What is there to fear?
What we need to watch out for is demons tempting us to do evil. You know that thought that pops into your head, that your first reaction is identifying that it's evil or wrong? That's not you. I don't know how demons can put thoughts in our heads, but God allows it, to test us for heaven. It is not wrong to be tempted, Jesus was tempted. What matters is your immediate reaction to it. Either you quickly flick it away and think of something else, or you consider it. In considering it you either use scripture against it, and thus condemn the thought, or you ignore right and wrong (quit thinking with your mind) and start thinking with your feelings / senses. And when you taste of pleasure you may give in to the temptation (sin)- which gives birth to spiritual death. "Do not be afraid of those who can kill the body, but be very afraid of God who can kill both body and soul."
