That's my point. I look at it and see an object. My friend looks at it and sees some sort of spiritual danger she can't quite put her finger on.
I don't worship it, I don't think it's going to "catch" my "dreams" - I just think it's a thing that looks good in the space. (I love American Indian stuff in general.)
I like Frank Peretti books as much as the next guy, but...
American Indians supposedly came up with the design (or adapted it) with the idea that it would ensnare nightmares, which they viewed as spirits, and prevent them from bothering the person in the place it was hung. They must not take it too seriously -- Indians are pretty private about their serious spiritual practices and don't just parade them to gawkers.
