I really like this thread because people can share their experiences without getting insulted, which sadly happens on many forums. I'll share two of my favourite experiences.
Some of you may know that I am involved in paranormal investigation, and I have been for more years than I like to remember these days. We were filming once in an old prison in Aberdeenshire. We were hearing some noises and I was getting frustrated because members of the crew were moving about, one was even crunching on a mint which was being picked up on the sound equipment. Everyone settled and suddenly a man walked by the door. He was no taller than 5ft tall, with brown tweed trousers, white shirt, a tweed waistcoat on and a matching flat cap. I charged after him thinking he was a member of staff just to say to stay still for a moment. The room was a dead end and he was nowhere to be seen. The curator later told us that he was a common sighting and despite the building being an old prison (where you might expect clanking chains and ghostly prisoners from the past haunting it), in fact it was said he was a member of staff in the 1930s when the building was used for council storage and died in the building.
Another one was in Inveraray Jail, we weren't filming as it was a private investigation but a member of my team was dragged up six stairs on a narrow and steep staircase. He was walking up the stairs behind me and suddenly there was a commotion and I saw him go up the stairs basically sideways without making any contact with them. The poor guy was traumatized by it. When we finished the investigation and went back to the hotel he slept on a chair in someone else's room because he didn't want to be alone. He left the team soon after as well.
I'd never seen any sort of physical interactions from spirits before that but not long after that I saw the aftermath of someone getting scratched in the Blair Street area of the Edinburgh Vaults, a good 15 inch scratch down the back of their leg.
I could go on but I've probably bored you all enough already haha.
What else?
I’ve always been interested in the supernatural and watch a lot of paranormal shows too! Not a ghost story as such but I visited a very old tourist attraction, in one of the older parts of the building there were some very narrow stone steps and as I went to step down I automatically went to lift up the bottom of my dress then realised I was wearing jeans 
I’m not sure if that was a past life memory or a sort of residual haunting but I felt a bit strange after, I’d love to know what I actually experienced!
