Monopsychism

Monopsychism is the belief that all humans share the same eternal consciousness, soul, mind and intellect. It is also a recurring feature in many mystical traditions.

Monopsychism is a doctrine of Sabianism, Jewish Kabbalah, and Averroism, and also forms a part of the Rastafarian belief system. This is similar to that of monotheism, which is a primary belief that all souls were once a unified soul in Adam. This is a main, shared feature of Judaism, Christianity and Islam.
