This probably won't count as a ghost story, since it is merely a strange experience that I need some answers to. This has happened twice now, both on weekend mornings, around 9 or 10 am.
My family has just taken a rescue dog into our home, and since he is new to our rules, he will sometimes sneak up the stairs when the stair gate is left open and sleep on the landing or, on more than one occasion, nose my door open and go into my room. To get into my room you don't need to turn the door handle because the door doesn't click when it shuts, so it is possible for George (my dog) to push it open. I always sleep with my door closed because I like to know when someone has opened the door, and it always makes a TWANG sound when it is opened and it creaks, so it is an extremely noisy door.
On this particular Sunday, I had woken up pretty late and was lying on my bed reading (I had been doing so for about half an hour) when the door opened. I said, "Yes?", thinking it would be a member of my family, but no one answered. I said yes a couple more times, then concluded George must have sneaked upstairs, so I got out of bed and walked to the door. I expected to see his face poking through the gap, looking at me hopefully, but he wasn't there. I thought he might have heard me get up, and rushed up the other flight of stairs to hide, so I called out loudly, "George!" but he didn't come running down. I was about to go up and search my parents' room when I heard him rush into the hallway from the lounge. He stood at the bottom of the lower flight of stairs, wagging his tail. I didn't go down and greet him because I wanted to read some more, so I want back into my room, shut the door, and got back into bed. Less than five seconds later, the door opened again, and then I thought, "Oh, maybe the front door is open, and the wind is pressing on the door, making it stay open." When this crossed my mind, I didn't bother to close the door, because I thought it would just open again.
Later, we were having dinner, and I asked my mum if the front had been opened at all before lunch. She replied that the first time it had been opened was after lunch, when my dad had taken one of my sisters to a party. That freaked me out a bit.
The next morning I'd completely forgotten about the strange experience, and I only remembered it when, about three weeks later, again on a Sunday, a similar thing happened.
Again, I'd woken late, and I had literally been awake maybe five minutes when the door opened, and I went through the same routine as before, calling out, then getting up to tell off the dog. When I realised he was downstairs, I remembered what had happened before and I was seriously spooked, because I couldn't come up with an explanation. I shut the door, and stared at it for maybe thirty seconds, before I decided it wasn't going to open again. I was getting back into bed when it opened very suddenly, scaring me out of my wits. I shut it again, and again it sprang open, almost straight away this time. I was practically pissing myself now, I was so scared, but the next is so freaky.
I went forward to close the door again, but this time I could feel something pressing back against me. It wasn't pushing hard, and I could still push it closed, but it opened again immediately, like someone was just nudging it from the other side. This happened a few times, before I sat on my bed and watched the door for a while. I don't know how long I waited, but eventually, I got up, opened the door, and went downstairs.
This happened almost a month ago, and it hasn't happened since. I just wondered if anyone has any info about what happened, or if they've had similar experiences. I'd really appreciate it if you comment below. Thanks for taking the time to read my story, and I hope some of you have some answers.
