I'm sure most of us with any age have seen unexplained phenomena. I saw a lion one night. But I was on acid

In all seriousness, whenever someone says they've seen ghosts, the 1st thing anyone who cares about them should do is suggest that they have their home tested for toxic gases. Many if not most cases of hauntings are actually atmospheric poisoning.

Pretty brave to post a comment like that on a website like this, that's for sure.

I'm not a believer in anything supernatural. I think most ghost sightings are cases of the mind interpreting incomplete information and filling in the blanks. I've also experienced the affects of extreme exhaustion to the point where I had mild hallucinations. Some of my fellow soldiers had more severe affects, and one even saw a ghost and led his team on a three a.m. ghost hunt.

When I was a child, I awoke in the middle of the night to see my mother bathed in white light, standing beside my bed. She looked exactly as she had in an old family picture. As she looked at me, it was as if she were saying everything was alright, peaceful. Slowly she disappeared, and I was assured she would be alright.

But as she slowly disappeared, something seemed off. Then I remembered. My mother wasn't dead. She was sleeping in the adjacent room. That was almost 40 years ago, and my mother is still alive.

If she had been dead, I certainly would have thought that was her ghost for years after...rather than a dream.

I used to have all kinds of vivid dreams as a child, and occasionally if I awoke too suddenly, I would still see things from the dream. Usually it involved spiders. (If "ghost spiders" were a thing in our culture, I'd probably believe in those for sure, and have a story to share with all "ghost spider" believers to pass around as evidence.)

i had a poltergeist once where i lived at the time. there is no such thing as a poltergeist but whatever caused the phenomenon hasn't got a name because it hasn't yet got an explanation, so calling it a poltergeist is all i can do apart from admitting it wasn't an actual spirit from a dead person but rather a phenomenon that i cannot explain.

A woman I dated told me about her four year old daughter. As she was going down the stairs at her home, she would say “careful little one, careful”. When asked why she said this, the little girl told her mom that “the old man goes down the steps with her and says it to me.” Later, at a grocery store my friend spoke to a neighbor who told her the previous resident had been an older man who died falling down the stairs.

The girl never had any other supernatural experiences.

Okay depending on time of day? You might want to check out "hypnagogic hallucinations". [en.wikipedia.org]

Other known causes are extremely strong Electromagnetic Fields and as Possum suggested below - having gas in the house.

Most cell phones can test for an Electromagnetic Field.

For gas? That's far more serious. Not sure who you'd contact - probably the authorities in your area. Do you have a CO2 alarm in the house? If so check the batteries. And test it.

Yeah seen a strange phenomenon myself

Inherited the family home & homestead ..where several family members had died of various causes in the century it was ours. Visiting friends & relatives would comment how the entire place reminded them of ‘the blair witch project.’

With ample opportunity and 33 years … how many ghosts did I see? None. Never never, never ever…. Cuz there’s no such thing ~

Yeah, you might as well tell the tale.

Psychological issues...

I have never seen a ghost, but I did have an ex-wife that could turn into a bat, fly out at night and suck blood from unsuspecting victims...honest.

I would be interested in your experience. Too many unexplained things in the world to hide away their evidence.

I have had a shared experience with a ghost or spirit, and a friend of mine has had a couple of experiences we can't explain. I have one unexplainable UFO encounter. I just put it off to the Universe being a lot more complicated than we can imagine, and we don't know what we don't know. I don't really think about it unless it comes up in conversation.

As a child, we feared the dark and the monsters or ghosts that might inhabit it, we avoided the dark, because we did not understand it. Older, we learn more about science, and eventually come to realize that it is the exact opposite . . . . we should, if we see something that we do not understand, approach it and learn about what it really is. For me, no ghost-like phenomenon has ever passed this test and proven to be real.

I thought I saw a dark shadow move across the ceiling.
Turns out I had floaters in my eyes.

I have a friend with a dog that looks exactly like Ghost on GoT.

No surprise since he is the same color and breed.

I have my own thoughts on this. I don't know if there is any scientifically proven or not.

Do not let my current position fool you. I have had ghostly experiences and supernatural experiences in my lifetime. Most of us have. It's just that today I know where most of them came from and how the mind is manipulated toward these events. It is all similar to our minds wanting to see patterns and how you saw that cloud that looked just like Jesus. The difference is that it goes a bit deeper than this, but it is all in your mind. Did it happen? Yes, but your interpretation of the event is flawed. This is the very reason that drugs and fasting are used for some religious experiences. You see what you are conditioned to see even if you do not understand all conditions of the event.

Met a ghost once. Well, from the band... serious side, I thought belphegor was in my house. I used some cleaning products to clean my toilet. I went to two churches the next day. Even did a confession. I was high as a kite for 2 Says! My business partners brother had to pick me up. My dad wanted to throw me in a nut ward. Be careful about chemicals!

Yup and I don’t speak if it

I have several times experienced unexplained phenomena

I would love to hear your story. I’m not opposed to the idea...

I have an odd unexplained experience from my childhood. Nothing in the past thirty years.
