1. Confabulation
This is a psychological term where a person unintentionally fabricates or distorts memories, and fully believes them to be true. It’s often used in clinical settings (e.g., dementia, brain injury), but can loosely apply to people who deceive themselves.
2. Pathological Liar (or Pseudologia Fantastica)
This refers to someone who lies habitually and often believes their own lies. Over time, they blur the line between fact and fiction in their own mind.
3. Self-Deception
This is a broader term where a person convinces themselves something false is true, sometimes immediately after saying it. It may be a defense mechanism or unconscious coping strategy.
4. Delusional Lying
In some cases, a person may tell a lie and instantly internalize it as truth, bordering on delusion. This can sometimes be associated with certain personality disorders (e.g., narcissistic or borderline).

5. Gaslighting (turned inward)
While gaslighting usually refers to manipulating others into questioning reality, some people do it to themselves—creating falsehoods they then accept as true to preserve a self-image.
