The worship that you hear of here isn't like that in a religion. Worship here refers to an act, not a belief that there is anything to be gained from it. Not eternal life, not sudden healing, not never-ending cookies(however my doll would get those if she just asked nicely enough).
A spell or a trance? Perhaps you are referring to Domspace or subspace. Why is it strange? Is it not similar to the way sports players talk about 'being in the zone' or when authors spew forth pages and chapters and entire books in a sitting because they're focused entirely upon what's before them? I have a feeling that you are misinformed, or have drawn your own conclusions after watching some show, reading some book, or having a close friend confide in you that their lifestyle is D/s and it bothered you. I do hope that we here can help clear the air, so to speak, and you can understand what it is you're obviously confused about.And I find it strange to hear that many are feeling such powerful emotions and devotion almost like under a spell or trance of some kind.
Again, this ties in to what I said in the first part. I'm sorry you feel this way, but perhaps through opening your eyes and your mind, you can see that we're not Devil-worshipers, which you alluded to with your parting question.Do you ever think about who is it that you are actually worshipping? What if it's not really a human at all? And if it's not God, then who is it?
Just my two cookie-scented cents.
