Does my house sound haunted to you?

Ok so we have a second house on the Isle of Wight, England, which is supposobly the world’s most haunted island. We come down most weekends and most holidays. Some really stange things have been going on lately, such as my mum was down the island on her own (with our dog Jerry), when the dog went very, very still, his hackles were raised and all his hair raised. He stayed like this in the same spot, staring at the same spot for about 20 minutes then his head moved slowly towards the stairs and he snapped out of this trance. My mum videod it a bit, she was really freaked out and waves her hand in front of the dogs face, tries to move him.. She even shoats at him and he didn’t move. she phoned my step-dad and told him what had happened, he said that was really unusual because Jerry is the best dog you could imagine, completely normal. After my mother hung up the phone, she heard someone run across the upstairs landing. She was home alone, but swears she heard this – clear as day. She checked upstairs, no one there. She even checked the attic, she was so convinced she heard someone, but didn’t see anyone.
My brother stayed down the island on his own one weekend. He’s the typical “macho” fearless 19 year old boy. Although he won’t fully admit it, he was absolutely terrified. He didn’t go upstairs the whole time he was there because he said he could hear footsteps, even thought they were being burguled at some point the footsteps where so loud. Our family friend on the island went and visited him and he was curled up on the sofa, food all around him because he didn’t want to move.
When we were all in the house (4 of us), I came downstairs in the morning and all the documents, tax bills about our business and everything were thrown all around the floor of the living room. None of us did this, something must have gone into the desk draw and messed it all up… There’s no wind in that room, and wind certainly couldn’t have opened a desk draw.

Stuff goes missing, appears again in weird places. No voices can be heard.. as of yet. but It goes unusually cold sometimes, heating is ALWAYS kept on full blast.

THE BEST PART IS.. My uncle goes to meetings about the ghosts on the island (weird, i know) but our house came up. We live in a modern semi-detatched that was built about 3 years ago, on the site of what used to be a bigger house’s garage. A man got murdered in this garage, my mother and her siblings all remember this murder happening in the 70’s. After the murder strange things used to happen in the garage.. like there was a spirit coming back to haunt or something. ANYWAY i was on google maps, looking at our house, and i zoomed out from street view to satelite view. satelite view is about 5 years old camera. on satelite view you can clearly see the old plot, and where our house is now there is a garage instead, part of a house and plot that covers our row of houses.

So, what do you think? I don’t mind if you think it’s bullshite, Any answers appreciated thank you 🙂
