Head in the clouds
If someone is being crazy and unrealistic, they have their “head in the clouds”:
“That guy’s constantly talking rubbish. He’s always got his head in the clouds.”
On cloud nine
If someone is “on cloud nine”, they are absolutely delighted about something:
“He’s been on cloud nine ever since she said she’d go out with him.”
Every cloud has a silver lining
This is a type of proverb which means every problem or bad situation has a positive aspect:
“I was really upset when she broke up with me, but I enjoy having more time to myself.”
“Well, you know that every cloud has a silver lining.”
“She lost her job but soon found something else she enjoyed doing.” “There’s your silver lining, then.”
