No. Sarah and other Reiki practitioners are not giving you their energy or receiving your energy.
Sarah and other reiki practitioners are like a hose for positive universal energy. Reiki flows through them and into you during a treatment.
Sometimes in everyday life we find that we “pick up” on other peoples energy or “vibes”. This is normal and natural; it is part of sharing our lives with others. If you are sensitive to other people’s energy in Reiki courses you learn how to protect yourself from unwanted energy, or you can find out more about this in your treatment – just ask Sarah when you make your session time.
