I grew up in a house that was extended around an existing building that was used as a church for the town while the new church was being built out of stone a few 100 metres away. When we replaced the floors in the old part of the house we found something like 380 Victoria pennies scattered under the floor mostly young heads and bun heads, plus quite a collection of bottles neatly laid out in rows.
Pretty sure the house was haunted but thankfully if so the ghost(s) were benevolent, it would mostly come down to small things going missing, then turning back up again in strange places. Also, anything electronic seemed a curiosity as every now and then odd things would happen like the freezer would be turned up to 6, and my parents always insisted 4 was high enough, you needed a 20c coin or flathead screwdriver and a bit of strength to turn up the dial. At first, I would cop the blame but I knew I was not touching the dial. We had a pretty big slow combustion stove/oven in the kitchen and sometimes in the warmer months it was not really worth lighting to cook dinner so mum often used those old electric frypans....she was always yelling at me for turning up the dial to full, but every time I swore to her that I did not touch it. A few times in the night we were woken to the stereo turned on to the radio but tuned to just static.
We had an open face copper kitchen clock in the shape of a frying pan, hung near the stove. It had a habit of stopping at 10:10, crazy thing was that it would discern between AM/PM always stopping at night. We thought it was the mechanism and had it checked, it was fine there was no obstruction that would force it to stop at that time as the hands moved into position. We always shrugged it off as "Henry" messing with us, then one night I was in bed and my mother screamed from the kitchen, I ran out with dad not far behind me and we were shocked to find the hands of the clock stopped at 10:10, however this time they were pointing out from the clock at 90 degree angles. I tried to rationalise it over the years thinking the clock might have been holding some kind of electric charge, reacting like bimetallic strips can bend with heat/electricity, I really can't explain it though.
Thankfully though it never went much further than that, mostly just a bit of trickery here and there. The house that we lived in prior to that one though was downright evil, Amityville Horror kind of deal. I was a bit young to remember it all, especially this long down the track but my parents tell me no one was ever happy in the house it felt like it was weighing you down. Apparently, I had constant nightmares and was always saying people were in my room at night and they would not let me sleep.
My older sister (who still talks about this) was home from school with a cold, both mum & dad worked and I was in daycare or preschool. She had been in her room in bed watching tv and had decided to take a nap, she woke to the sound of someone in the kitchen, the clink of a teaspoon on a cup and the kettle boiling. She thought our mother was home and called out "Hi mum, can you please make me a cup of tea too?" there was no response, so she called out to mum again and rolled over in bed to see what she describes as a figure of an old lady standing in the door of her room, she says the figure was not quite corporeal, and that the woman put her finger up to her lips and said "Shhhhh, go back to bed dear" my sister freaked out and hid under her covers until mum got home with me around 4 pm.
When my parents decided they had had enough of the place, they had to get an electrician in to do some rewiring. The guy knew the place but said to mum and dad, that the house was not built there but relocated there. Turns out the house was sold to the previous owners on the cheap as a multiple murder/suicide was committed in the house. From what they found out later is that a guy killed his entire family in the house with an axe and a hammer, then hung himself. To make matters worse there were existing stables on the property where another separate man had hung himself only a couple of decades prior.
I have also seen Min Min lights out the back of Queensland while travelling up to the Cobourg Peninsula for a fishing trip, pretty scary at the time but some scientist from the University of Queensland now explains that it is just refracted light trapped in a layer of cold air. During a storm my grandparents had ball lightning come in the back door of their house float around the lounge room before hitting the TV and then going out the front door.
