I went with a friend to look at a beach cabin that he wanted to buy a couple of years ago and it had an actual motel vibrating bed. I had never seen one in a private home until that time.
I slept in a magic motion bed in Altoona, Pa. It was a rustic Hotel while I was in training for Greyhound.
It was soo much fun looking for the bathroom and there was a hole in the floor......
LOL
Open another door and there was the potty room!
Tin roof, rusted....
I wonder if such a thing would lull a younger child to sleep.
My aunt used to put my cousin in the car and ride around to send him to dream-land. (Think he was difficult? LOL) Must be the rocking and vibration that does it.
Could it be womb-like vibrations such as when momma was walking aorund?
