Dreamcatchers are protective talismans which are used to protect people from nightmares and negative energies.
You should hang your dreamcatcher over or near your bed to shield you when sleeping or at an entry point of energies in your home such as windows and doors. 
 
A dreamcatcher should be purified frequently by hanging it at your window so that it catches the sunlight, this is important because the sun acts as a cleaner for the bad negative dreams and energy caught in the web.
