Perhaps I have a gremlin in the kitchen or something. I hadn’t used the machine for at least two weeks and it just suddenly started operating. Nobody had touched it or even gone near it.
Weird. 
Run! RUN!
Seriously, check the appliance and see if it’s plugged in. Do you have a light system that turns the lights on and off by themselves periodically?
Mine tried to commit suicide, it walked right off the edge of the counter and smashed onto the floor. Got a big dent in one side, but it still works. But I have it on suicide watch now.
The other day mine got pissed off and started making cake instead. It now refuses to talk to me unless I refer to it as Marie Antoinette.
No matter what ingredients I put in mine, it always produces bran muffins.
I think it’s trying to tell me something.
Once my Bread Maker started making bread on her own. I told her “NO! First you clean the basement, THEN you can make dinner!”
*not true in the slightest
I had a similar experience. I was cooking with an electric skillet and apparently the thermostat had broken and the skillet just kept getting hotter and HOTTER and threatening to boil over all over the floor, etc. The scary thing is that I was watching the movie Maximum Overdrive at the time.
When it starts loading itself with ingredients is when you should really start to be concerned.
Open the top…see if you hear a voice say “Zool”
No, that will be good. At least then I’ll get a new loaf. 
All it did yesterday was mangle the measuring cup that I keep inside it.
Now we understand- would you like it if someone stored a measuring cup inside of you???
I think the machine was sending you a message- next time it’s the head of a loaf of bread in your bed…
Between this and the stove that lights itself, I think we should be worried. Or possibly prepare for yummy meals, made by the appliaces themselves, of their own free will.
In completely-unrelated news, did you hear about the virus-based nanoparticle that has been modified to be electrically-conductive?
Bah!
You want a true tale of electric terror?
I was woken one night to discover my 12 inch cucumber had begun singing, all by itself! You try lurching out of bed to fin a dancing cucumber demanding to know where its hairbrush has gone.
After that night, I took out the batteries.
