Idiom:  Sleep like a log

Meaning

Look at the picture and try to guess the meaning of the idiom 'sleep like a log.'  

Sleep like a log:  to sleep very soundly (deeply) — so well that noises don't even wake you up.


Notes:     

In case you don't know what a log is, it's a large part of the trunk of a tree that has been cut down. So it's that large, long, round cylinder-shaped tree portion on the bed in the picture.

You probably wouldn't think that a log would easily "toss and turn" (move around to different positions) during the night while it was sleeping. It's so heavy and big it would just stay there in the same position and sleep. A log is very hard to move (or disturb).

So this is a really easy idiom to remember. It's used frequently in every day informal English.
