I slept like a log.
Now what is a log? In Japanese, a log is: 丸木 (まるき).
And when you sleep like a log, you slept really deeply and soundly without waking up till morning. You didn't move at all just like a fallen log. In Japanese, to sleep like a log is:
グースカ or 寝付がいい (ねつきがいい)
Now, when you CAN'T sleep well we usually say:
I was tossing and turning all night.
Meaning you couldn't fall asleep and you kept moving around in your bed so you slept badly. Which in Japanese would be:
輾転反側 (てんてんはんそく) or
寝相が悪い (ねぞうがわるい)
While being unable to sleep well is:
寝苦しい (ねぐるしい)
So here are some example sentences:
A: Did you sleep well?
B: Yeah, I slept like a log~! I feel great!
Summers in Japan are too hot! I spend the whole night tossing and turning and feel terrible in the morning! Maybe I need to buy a new air conditioner...
So I think that is it for March, see you in April for some more mini-lessons!
