The last couple days we had really hot summer temperatures, peaking at 38 degrees. Yesterday night, the house started making noises after I fell asleep. At first it sounded like someone was kicking the walls, and a broom fell down, and then kicking my own bedroom door which jolted me awake. My housemate came home and I told her about it, she stayed up a bit to see if it'd happen again. I walked into the bathroom and promptly heard a banging noise twice in a row. I went into her room asking if she heard that and she freaked out because she thought she saw me walking down the hallway into the living room and I made that noise.

-Skipping a lot of attempts to figure out the source of the noise which were determined to come from upstairs, I realized it must be the metal under the stress from all the heat since it had been happening day and night (which were both really hot). Last night the temperature dropped to 23 and the noises stopped. My housemate doesn't like my "metal expansion" theory however and keeps insisting it's "demonic harassment" from this spiritual war going on. She also said "If it's metal expanding then how does that explain that I thought I saw you walking down the hallway?" Oh gee, I dunno. Maybe something to do with peripheral vision and you not paying attention?

I'm sorry but we've both slept through the bangs and cracking and we're still alive, but now we have to have a pastor come to our house and exorcise the oh so evil noisy demon. I might believe you when it starts picking up knives and flinging them at us but until then can we please just let physics do it's thing and live in the 21st century?

Metal in house most likely expanding under heat, housemate thinks it's a demon of harassment and called a pastor in to get it exorcised.
