you should get it blessed by a shaman or pray or do a spell wit the great spirit, say a prayer about how the negative and evil spirits will be absorbed into the web of the dream catcher pray that the nightmare get caught in it and hang it above your bed and that should work, also if you have a toy spider ring or any kind of fake spider object put it in the middle of the web and pray the spider eats the evil spirits and pray the feather wards off the evil spirits. and that should work.
also feel a web energy in the web of the dream catcher, feel it as a sticky substance and feel the soft web upon the web of the dream catcher and feel it as a positive feeling, that should work also.
Dream catchers were originally made by the American Natives, to put in the cribs of children, babies even, to stop bad dreams from entering sleep. The dream catcher is hung by the head of the sleeper to catch bad dreams in the web. When the sun comes up, they burn away. The bead in the middle catches the good dreams, and the feathers that hang from the bottom are so the good dreams rain down on the sleeper. Its nothing really magickal. It was a charm for the children. I have one hanging on the wall at the head of my bed. A friend made it for me. I, in turn, have made several for my friends and family. So there's the story. Blessed Be...
I simply blessed mine with word power and a herbal mixture that I burned while holding the Dream Catcher over it (It makes it smell nice, too. But be careful not to burn it!)
Then you can hang it above your bed, and if you want, before you go to bed you can ask the dream catcher to guard you from any bad dreams
Dream catchers work by: Catching the "bad dreams" in the web, and alowing "good dreams" to slip threw the hole in the midle. 1.Haveing something in the center is ok, dreams can slip threw;) and its also nice to have a piece of "you" atatched. 2.Not all nightmares are "bad dreams"..they have thier purpose like everything else... 3.Dream catchers work on the physical relm and the dream relm, so its basicaly an inter-reality tool. The "dream relm" is a relm of the mind, and internal self, so i suggest u fill ur mind with native american stories of dream catchers. Sweet dreams kido :)
