I previously mentioned ignoring it, it works. I grew up in a place that was haunted, as a kid it was fucking terrifying, bed shaking, lights going off and on by themselves, tv changing channels (old tv no remote physical dial), radio changing stations, voices and shadows, stuff going missing randomly and fucked up smells. As I got older I actually got used to it, and by the time I hit my angsty temperamental teens I found it merely annoying, and would tell it to fuck off because I had other shit to do, and eventually it just went away. These things feed on fear, and if you're not afraid of them and they're just a nuisance to you, they'll find somewhere else to go.
