Yeah, it cracks me up.

Well don’t you guys agree if there’s is a bad spirit then there do exist gods too as it said scripted in almost all of the religious scriptures? So technically if a person believes in god then there are more than 80% chances that he/she will remember the god whenever that person experience some hallucinations of ghosts.
P.S - I don’t wanna hurt anybody’s sentiments/emotions that was just my point of view.

Hm... I wouldn't readily believe anyone who told me they saw ghosts, but I wouldn't really throw away the idea either. If there are ghosts, it doesn't necessarily have to be automatically linked to god. Maybe the whole idea of god came from perceived sightings of "ghosts" and generations of people's imagination went wild with it. As it is, we understand and can prove general laws of physics that we can see and measure but it wasn't up until a few months ago that the theories of gravitational waves were actually detected and proven. There's still a lot we don't know and until we actually sit down, study the phenomenon (whatever it may be and however absurd we think it might be), measure it, and cross it off the list, we can't actually say it doesn't exist with full certainty.

Surely a true Atheist has no belief in anything supernatural or paranormal?

My wife is an atheist and she believes in an afterlife. so what?
I think it's just too difficult for some people to believe they'll never see their loved ones again.

First, I don't call myself an atheists. There are a lot of things I don't believe in, I generally, think of myself by what I do believe, not what I don't. Secondly, it isn't so much that I believe in ghosts. It's just that Ive had a couple of experiences that were out of the ordinary. The first was in the month of May 1968. I awoke in the night to settle my new born son who was crying, the second time when i picked him up and carried him into the next room so I could sit down I could I could hear my nephew laughing. He assured me he was okay and was very reassuring. I didn't assume he was dead, or a ghost, i assumed he was okay. A day later I found out he had died in Vietnam. Next, my 3 year old daughter was painting a picture for me and like all mothers I ask what it was. It was a man under the water with his boat above him. I dutifully hung her picture on the refrigerator. We ate dinner and a little later we got a phone call that Grandpa had drown while sailing that afternoon. When pressed about a belief in gods, I don't believe, although I do sort of believe in ghosts only because that seems to be the correct term in English. To me spirit seems to imply a soul, where as ghosts would just be the electrical energy that each of us has.

Under dire stress sometimes people see things or people who are not really there. They are images created by the mind. Everything we see is an image created by our minds.

I know people who report experiences with ghosts. They are sincere, and I do not laugh at them. Some of the stories are verified to an extent, but to a closed mind no verification is ever enough.

An atheist doesn't believe in a deity whereas a ghost is an apparition of a dead person that is believed to appear or become manifest to the living, typically as a nebulous image. These two things are not contradictory and therefore you're laughing at a connection that exists in your mind but not in theirs, or in the definitions of the terms.

There are also atheists who are anti-vaxxers, strange enough.

Why would believing in god mean you don't believe in ghosts or anything else?

Ha ha.

Gives me a chuckle aa well

The center stack of my Chevy has a gremlin.

A-theists do not believe in god(s), they can believe in ANYTHING else. Ghosts, demons, witches, crystals, bigfoot, astrology, just not god(s).
