Background-
I've known since I was young young that my childhood home had something not right about it; Mimics luring myself and others into the dark, shadow figures that spy from around corners or duck around door frames, scratches, bruises, a feeling of being watched, reflections moving separately, weird smells, cold spots, dead flies on the windowsills, mold no matter how we clean, animals seeing things/getting defensive for "no reason", things moving and being thrown, the absolute works. Since leaving I've realised all that "paranoia" of being watched has just gone, no shadows, no unexplained injuries, ect ect... But now that I've been visiting again I find myself irrationally irritable, nauseous, the paranoia returns and a wave of general anxiety wraps around me. I've had partners wake up in that house panicked, friends say they feel overwhelmed in some rooms and have to leave, you get the picture.
I still have family who live there, I've noticed them getting more irritable, forgetful, "stupid", generally drained like it's feeding off them more now that it has less people to torment. I please want any suggestions to get rid of it, I've tried sage, bells, the basics but I'm willing to go full exorcism with this because I know when they move it'll be the next family's problem.
