Bad Dream Catcher

My 4 year old granddaughter has bad dreams.  Her parents have tried all kinds of ideas to re-assure her that they are only dreams and not real, but she's not buying it!  So one night I was babysitting and had to go all around the room and scoop up all the bad dreams into my hands and throw them out the door.  The next day I was at my favorite Dollar Tree and VOILA a bad dream catcher! (A.K.A. butterfly net)- so now before her parents kiss her goodnight - they wave the bad dream catcher around the room and it's been days since she had a bad dream.
