Thanks in advance!

How would you say the following when a child is going to sleep(what do Russians say to their kids?) Please highlight the stressed vowels.

Sweet dreams.
Have a good dream.
Do you remember your dream?
Was it a good dream or a bad dream?
Tell me about your dream.
Maybe your dream will come true.
Don't worry, it's only a dream.

Is there a Russian word for: dreamcatcher
