Machiel is a gifted dream worker recognized around the world for his research and work on dreams. Answering his calling as a dream worker, he has written Dream Guidance (Hay House Publishing), founded the Jung Society of Utah, and Jung Platform—a leading organization on Jungian and depth psychology. Together with his sister Akke-Jeanne Klerk, he has created many dream summits on Jung Platform. Machiel continues to give lectures and workshops on dreams across the United States, Africa, and Europe. In therapeutic practice, dream work forms a central element in his approach to healing for his clients.

In his early twenties, faced with challenges, Machiel found a book by Carl Jung by chance. He has ever since been inspired by dreams, their guiding and healing powers, and has nurtured his special connection with them. Machiel has studied different dream traditions and has worked with African shamans, western dream workers, eastern dream traditions, and Jungian psychology, etc. integrating them into his unique way of engaging and being with dreams.
