Ever since I moved in, my house feels like someone else is quietly living with me

I moved into this place a few weeks ago, and something has felt off—not in a scary way, just… strange. Things don’t go missing. If anything, they get put back. Like I’ll leave something out, and later it’s exactly where it should be. At first I thought I was just being forgetful. But it kept happening in ways that didn’t make sense. One night I left the kitchen light on. When I woke up, it was off. No big deal, except I live alone. Same with doors. I don’t always close them fully, but I’ve started noticing they’re always properly shut later. Nothing ever feels out of place in this house. If anything, it feels more organized than I keep it. And that’s what makes it weird. It doesn’t feel like something is trying to scare me. It feels like something is trying to… help.
