Sleep TIGHT and sweet dream. I read a article today. It talked about the origin of "sleep TIGHT".
Following it's the article:
______________________________________________________________________________________
Nowadays, bed frames are made of springs. However, old bed frames used ropes pulled tightly between the frame rails to support a bed.

When the rope became too loose, the bed would sag, making sleeping very uncomfortable.

Tightening the ropes would eliminate the discomfort and help one to have a good night sleep.

Hope the story is true. How interesting the story it is!!!
Now talk about your thought. haha

Hmm, where have you read this story from? It sounds like a textbook of physics :)
The story is a half true. Because "nowadays" I am sleeping on the bed with no springs nor ropes :P
