Just for some background info, I'm only 22, I have no children and I have no younger siblings that live with me. It used to be just me and my mum who lived together while I save up some money to find my own place and move out. My fiance has also just moved in with us but at the time this story took place, he was living elsewhere until he finished his job and moved up here to be with me.
So as I said, this story takes place a little before my fiance moved in. I was lying in bed alone one night (in the pitch black) facing the wall as I usually do most nights away from the rest of my bedroom; as well as away from the bedroom door behind me. I was sort of in that state between being half asleep and half awake when I suddenly started to hear my bedroom door begin to open and brush against the carpet. I didn't really think anything of it, though I have no idea why I didn't react as my bedroom door doesn't swing open on its own as it really needs to be pushed with a bit of force to open/close.
A little while after my door opened I started to hear small footsteps entering my bedroom slowly, sort of dragging and shuffling against the carpet as if whoever or whatever it was, was wearing slippers. I lay and listened as the footsteps seemed to get closer and closer to my bed, which is not very far away from the door because my bedroom is quite small and weirdly shaped. The footsteps eventually stopped, right at the side of my bed - nearer to my head than my feet. I sort of froze and didn't know what to do or what to expect next when the bed felt as if someone small and young had leant against it; making me roll backwards slightly and then to my absolute horror I felt a small hand reach out and tap me on the small of my back three times and a child's voice say "Mommy?".
I have never leapt out of bed so quick in my entire life. No one was there when I turned around or when I turned on the light but I ended up sleeping downstairs with the TV and lights on and was reluctant to even go back into my bedroom.
There are numerous incidents where I have heard children laughing and giggling near my mother's bedroom door, and when I was a child me and my best friend even heard a small baby crying out of nowhere while we were playing Sims quietly on the computer with the sound turned down very low.
