Psychological Projection.

Psychological projection or projection bias is a psychological defense mechanism where a person unconsciously denies his or her own attributes, thoughts, and emotions, which are then ascribed to the outside world, such as to other people. An example of this behavior might be blaming another for self failure. The mind may avoid the discomfort of consciously admitting personal faults by keeping those feelings unconscious, and by redirecting libidinal satisfaction by attaching, or "projecting," those same faults onto another person or object.
