Some paranormal experiences

So hi, my name’s Kaolant and I’m from Australia. I have a couple paranormal experiences I would like to share. 

#1 is from about a year ago, in a really really small town. I’m just walking around, when I notice the town hall’s door is slightly open, so I think ‘Huh, that’s weird’ and go to check it out. (The hall was built in 1898, so pretty old.) I open the door and inside there’s like a long hallway that leads into a larger room. At the end of the hallway there’s another door. I hear footsteps, the doorknob turns and the door swings RIGHT OPEN and no one is there. I run out of there and grab my younger brother, who says he saw the door slam shut.

#2 is from about 3 years ago when I’m camping in the desert. There’s like this really really old semi-abandoned settler house from the early 1800s and the people who own the land rent it out to campers. Most of my family are inside sleeping, and my dad and I are sitting outside near the campfire, when I see something in the trees (there’s like about 100m of flat soil and then trees in the distance.) I distinctly remember a female face appear and look at me from the trees, and then she was gone. 

#3 happened to my mother about 10 years ago. She’s a nurse, and she’s working in a ward with all male patients. It’s very early morning (like 12-1 am), when she suddenly sees a little old lady in a hospital gown slowly walking down the hallway. Since she’s tired, it takes a few seconds to realise that it’s a lady in a men’s ward, and she’s thinking maybe she got lost and needs some assistance. Down the hallway, the way the old lady was headed, there’s two storage closets and that’s it. No windows or anything. She gets up from her desk, checks both rooms and there’s no sign of any old lady. It could’ve just been a hallucination since she was so tired and it was so late at night, but I’m not sure lol.
