What are dream catchers supposed to do ?

The myth relating to dream catchers are that they are meant to catch your bad dreams so you don’t actually dream those nightmares. That doesn’t mean they stop all dreams getting through they let the good dreams through for you to have a pleasant night sleep.

Do they work?

Dream catchers are regarded as a legend rather then a fact. There is no scientific evidence that they actually work. However there is no proof that they don’t work and some people who suffer from really bad nightmares see dream catchers as a natural and cheap cure for their bad dreams.
