Bolt out of the blue
sudden and unexpected
chasing rainbows
trying to achieve something that's unrealistic
once in a blue moon
very rarely
don't have the foggiest
confused and having no idea
every cloud has a silver lining
there is good in a bad situation
dry spell
a long period without success
dancing up a storm
using a lot of energy to dance
rain on someone's parade
spoil a person's pleasure or plans
blow everyone away
easily defeat the competition
chill out
relax
steal someone's thunder
take attention away from someone
made in the shade
in an ideal situation
