Your experiences are common among reiki people. Just go witht he flow of it all. It is your head which wants to ask questions. In your knowing, you know. All of us has to clear ourselves of old emotions. Eventually you will not have an emotion left. Emotions are in the brain, they are thoughts masquerading as feelings, but they are not. Your true feelings are love, joy, etc.
Other answers will use words you may better understand than mine.
