I have a fair few, i'll share some. Whether or not they are explainable or not, i suppose they could be.
1. This is an account from both of my parents, from some 30 odd years ago.
Staying up on the Scottish borders at my Uncles house, which is an old detached farm house, in a fairly sparsely populated area not far from Kelso. One night, my dad was awoken to a rattling noise. It was pitch black, no street lights etc... The rattling got more and more ferocious. At this point he was out of bed and was scrambling for the light switch and my mom was awoken by now asking what the noise and fuss was. Finally, my dad found the switch and the moment he flicked it, the rattle stopped and the dresser at the other side of the room was perfumes and the wobble of the bottles were still visible but that was all, nobody there. Maybe a tremor or mild quake? None were recorded in the area and nothing else was moving such as the light shade in the ceiling etc...
2. More personal to me, but after my Nan died after suffering with Alzheimer's for a while before, i was awoken in my bed. I sleep on my side or front mostly with my arms tucked under my pillow. I felt a definite hand stroking on my back. Gently and softly even familiarly. I turned my head expecting to see somebody, but nobody was present and at that moment i felt a waft and i felt "it" leave. It was winter time and no windows were open and it was a fairly new house at the time. Many explanations, i know. But a few days later after catching up with my sister, i mentioned it and i was amazed to hear that she had the exact same thing happen to her on the same night and to be clear she lived in a different house. The story gets stranger or more coincidental, whichever way your persuasions fall but my Nan's older sister lived many thousands of miles away in Australia at the time. Just 6 hours before he younger sister died, she said to her son that she must go now and she died. She was of sound mind.
3. Is an account of my friend. Which had a remarkable similarity to yours. One night, my friend was awoken to his then Girlfriend screaming. At the foot of the bed was my friends Dad. Who had just recently died over 200 miles away, unexpectedly and suddenly in a hotel room. After my friend woke up, stunned of course and unable to say anything. His dad or whatever figure it was just seemed to just fade away. They both saw it and swear by it.
It frightens people to admit it i think, but i have many more things that has happened to me and people around me. Im not a "ghost hunter" or have any real interest in it. I just have experiences and accounts. Im open to logical suggestions always have been but not a lot explanations have left me satisfied.
