Investigators could tell the room was haunted, if not out right cursed, because of the sheer amount of things in it that seemed to have a purpose but produced no discernible effect. Light switches that when flipped did nothing. Outlets painted over that after carefully sloughing off the paint, which ended up in rainbow sherbet clumps on the floor, drew no power. A side panel door to a sheer brick wall with maybe a half an inch of clearance. A composition notebook would barely fit in it. There were built in speakers to the blonde maple wood but when you chased the wire to what should have been the access panel, the wire just dove into a solid cube of cement. The drawers were cut at triangular angles so pulling one out also meant possibly topping all of everything onto one's foot.
The main color was a had too much ice cream after dinner mint green with too much blue but still enough green. Then deep mahogany trims almost black for stark contrast. But under all that paint were dozens of layers in wilding hues. The walls seemed almost an inch thick with just paint, making the whole thing smaller and encroaching.
The rest of the house? That seemed fine and quite dull. But, in the backroom, everything seemed amiss and annoying. In the middle of it there was a warm spot that seared from an invisible source while the rest of the room remain stuffy but tolerable.
One investigator tried to bring in some fresh air and opened a window to find that the wire window screens were just finely painted lines on translucent paper. He removed it and poked his head out the window to see the small backyard and then a broken floodlight glued right by the window. Broken in that each head drooped on exposed wires to the side. He told another person to flip all the mysterious light switches and nothing sparked from the flood light.
They all stood in a circle while investigating, their backs to each other, as to make sure nothing slide out from behind a pulled door or curling floor board. But they just found more inconveniences, the angriest one being the tacks arranged like a punji board on the threshold of the sole closet.
The owners, chatting with the group after the walkthrough in the room, asked what to do. The investigators suggested to board up the room and not bother. Whatever haunted it seemed content to form whatever needling grievances from that single space. "Make it a room to go in every one in a while and spook a visitor. A real mother in law suite, if you get what I mean!" The assistant then mimicked banging on a pair of cymbals. Ba dum dsh.
"Is this common?" The owners of the home demanded.
"No, not too common. Poor maintenance is one thing. Landlors who paint over things and decide to cut costs but a space like that, which seems to find something new and irritating upon each entry is not. A real mystery spot. Ever seen things run up walls in it?"
