I haven’t had a lot of ghostly experiences but I did have one that was very convincing.
It was in the early 90s. It occurred very early, before anyone was up, in a care home I worked in.
It was summer and broad daylight. I wasn’t in the least scared and felt no sense of evil or menace.
What happened was that there was a bathroom for people who needed assistance and it had a sort of chair lift device over bath.
What happened was that as I walked past the door handle was going up and down rapidly and repeatedly like someone was trapped or the door was stuck.
There was a resident who used to wander and I thought it was them so I opened the door and there was no one there. The handle rattling stopped for a moment and started again.
I kind of shrugged and went on my way, thinking that was odd.
I didn’t think much about it but I mentioned it to my dad who was a carpenter and knows a lot about buildings and I asked if he thought it was subsidence or something.
To my surprise, he said he thought it was a ghost. He’s a very rational down to earth bloke and this wasn’t what I expected.
There is a punch line to this and it is that I later found that a resident had died in the bath. They had filled the bath, suffered a heart attack and fallen head first into filled bath.
I don’t know what I saw if it wasn’t a ghost. That’s actually more rational that any other explanation.
I’m a Christian so I do believe in spirituality I suppose. I think most people’s experiences have non supernatural causes and I think shows like “Uncanny” and “Most haunted” are silly.
But every so often something happens that you can’t explain. So I guess I do believe in ghosts but I’m not gullible and I’m not massively into the idea.
I think the OP’s friend’s experience doesn’t sound very likely to be supernatural.
