Okay, this is a nice story thats kinda similar.
We were playing hide and go seek in my friends REALLY small appartment (living room with attached kitchen, upstairs with 2 bedrooms and 1 bathroom)
It was 4 of us
The finder had to listen to a whole song by whatever artist (had to be more than 4 min) with headphones really loud
on one of my turns, my friend Jared decided to take all the trays out of the dish washer and hide them in the cubbord under the sink and climb in the dish washer.
I found the other 2, and we spent the next 10 minutes trying to find him.
We heard him yawn, and snuck up on the dish washer, locked it, and turned it on.
He heard "thud thud thud" from the little spinny thing on top that sprays water hitting his head.
We let him wash for like 3 minutes before we turned it off.
