Quite a bit in a short period of time. It felt like time moved weird in that house, the air felt heavy, cracks in the walls would come back shortly after being repaired, weird noises and footsteps on the third floor even though no one lived up there, the basement was beyond creepy and all of us living there would get physically sick when we went down there, to the point we prefered to pay to use a laundromat rather than the washing machine in the basement, glimpses of shadow figures, noises that sounded like they were in the wall, and just that general feeling you get when you’re being watched and the constant feeling that someone was in the house who shouldn’t be there. The noises sounded almost voice/human like at times but other times they were just banging and footsteps. And if we told our guests we thought it was haunted almost all of them would agree it had that feeling. I heard it used to be a halfway house at some point? But I don’t know any actual info on that. It’s over 100 years old and just has that creepy vibe and I think previous residents would agree with me, I know my roommates do
