I'm a 19 year old girl from the west of Scotland, myself and my family have always had connections with ghosts and spirits and talk openly about them so it's quite normal for us. I live in an old miner's cottage which was built in the 1800's and before I lived there my uncle and cousins did.
One day I watched my cousin as she sat at the bottom of the stairs looking up, I asked what she was looking at and she just replied with 'the man on the stairs'.
A few years later I moved in with my mum and sure enough every night I can hear distinct heavy footsteps walking up and down the stairs. He seems to be pretty chill and I've never felt threatened in the house with him. He's affectionately named the man on the stairs.
Another time I was having trouble in my own room with a spirit and would wake up with things thrown on me and my belongings moved. I wasn't able to sleep in my own room for about a month until I finally went to my parish priest who agreed to come and bless my house for me and the trouble died down there but every now and then I begin to feel very uneasy in my room. Not sure if I should get it blessed again as I definitely do not want it to get as bad as it was before.
I can happily sit in the presence of ghosts as long as we both go about our own business and I do not feel threatened.
I've had many more encounters many not in my house which I would be happy to share as I've tried to talk to my friends about it but they're very sceptical and it's not easy to talk about it with them.
I was also going to refer you to rookdygin's profile for the cleansing method that many long-standing members swear by.
Thanks for sharing your experiences and I look forward to reading more - especially since you're so at ease in the presence of ghousties. ^.^
