This is a weirdly specific question, but hey, I get it. If I moved into a place with that kind of history, I'd be freaked out too. My first step would be a serious, deep physical cleanse—like, hire professionals to scrub every surface, replace carpets, repaint. For me, the fear is tied to tangible residue as much as vibes. I'd also research the actual events, not the rumors. Sometimes knowing the cold facts, the ‘who, what, when’ demystifies it and makes it feel more like a sad historical footnote than an active haunting.
Then I'd shift the energy entirely. I'm talking major redecorating, loud music, filling the space with friends and life. Burn some sage or incense if that's your thing, but honestly, throwing a big party feels more effective. Claiming the space for new, happy memories is the real trick. I read a book once, 'The Sun Down Motel' by Simone St. James, which is about a woman investigating a murder in a creepy motel. The story shows how confronting the past head-on, but then firmly closing that door and living your life in the present, is the only way through that kind of fear. My final move would be to install really good lighting, inside and out. Darkness lets the imagination run wild.
