Final answer:
The process wherein an individual cannot clearly differentiate between their emotions and thoughts and those of the environment is called confluence.
Step-by-step explanation:
The process of blurring the differentiation between the self and the environment is known as confluence. This term describes a state where an individual's boundaries with others become so fluid that they struggle to distinguish where they end and others begin.
This concept is relevant in various therapeutic and psychological frameworks and is distinct from other processes like projection (attributing one's own feelings to others), retroflection (turning back onto ourselves what we would like to do to someone else), and introjection (taking in the characteristics of others).
