You have interpreted your own dream. The most interesting thing about us human beings is that God has given all of the instincts we need to judge and interpret for ourselves the situations we find ourselves in.
You had been skeptical of the 'church' you've been attending to begin with. I believe you were receiving confirmation from the Holy Spirit that what you felt was correct. The attractiveness of the pins coupled with your uneasiness to wear them seems as though the term "all that glitters is not gold" was your definition of the Reiki church. (The first instinct is usually the correct answer).
Once you made your decision in your waking hours it seems as though God was leaving you signs everywhere to confirm that what you felt about the church was true.
I feel you will find a fellowship that will be a good fit for you. Continue to let the Lord lead you and you will be blessed. You already have God's angels fighting your battles-those were the signs!!!
