Living abroad, I moved into an older apartment. It has two floors. Floorboards in the whole apartment are creaky, so when someone walks it is very loud.
On many occasions, I have heard footsteps - clear as day - walking across the floor above me. Absolutely undeniably in the bedroom above. We are on the top floor, so there's no chance it's coming from a different apartment, and it's very clearly overhead. I'm not the only person who has witnessed it. It happened when I first viewed the apartment and the estate agent, DP and I all acknowledged it. My friend has heard it in the middle of the night when we were sat on the sofa chatting away (came to stay for the first time in a long time and we were sat up chatting!). She literally looked terrified and grabbed my arm and was so surprised, she said she'd never experienced anything like that so clearly before.
The bathroom door has this weird, frosted glass panel in it. They're common here. I've seen, clear as day, someone moving in the bathroom. I nearly had a nervous breakdown, as it was so clear, and looked like someone dressed in black passing the window. I flung open the door and of course, nobody there.
The weird thing is, this apartment has the warmest, safest, and most welcoming feel to it. I've never felt anything like it! As soon as I entered the apartment to view it, I could feel this wonderful, warm presence. Like I knew that the previous owner was still here, and I knew that they were not a threat, but a positive presence. I know that sounds absolutely mad! My children have said, by themselves, things that indicate that they feel similar (i've not discussed it with them because I didn't want to scare them, but they've brought it up on their own. We all feel that the apartment has the vibe of an elderly, kindly man who woman who lived here before and isn't ready to move on yet. Weirdly, we don't want them to leave and find their presence comforting. My friend suggested sage-ing the apartment but I don't want to, in case it works and I make this kindly presence leave before they are ready to!
