I used to live in this flat with my mum and cats in England, Essex. Not really sure of the history of the flats or when they were built on with my story.
Probably about a month before we moved out I was about 11 at the time. I sometimes slept next to my mum in her bed. This one night while I was sleeping, in my dreams I could feel like a dozen hands tickling my back right on the spine. I woke up and could still feel the tickling which went on for a while. I had my back towards off the bed I and when looked behind me all there was was darkness. My mum had her back to me so it wasn't her and obviously not the cats.
On my 15th birthday my mum had a date so that night my friends came over for the night. One of my friends said he was tired whilst my other friend was playing PS3 in my room. I told my friend he could rest on my mum\'s bed for a bit. After a while we went and woke him up. Time was about 1.00am. We babbled and talked. My friend said he had a weird dream that someone was tickling him, but no one else was in the room at the time.
After we had moved out, I told my mum about the tickling and she said "oh I know I have felt it too, if I slept on the right side of the bed, maybe the mattress was haunted". We both laughed and never really talked about it again. But the tickles were so... You could feel them so strongly on your back; it was creepy waking up in the middle of the night like that. I wasn't ever sure if I was just tired at the time and imagined it but it was coincidence that it had happened to three people. I'm just wondering what could have been reason of all this?
Okay, on the serious note, I've heard and read about certain objects that appear to have an otherworldly attachment to it... So I figure it wasn't harmful which is good.
