Selfinvasion

Selfinvasion refers to a fictional concept where an individual experiences a profound internal disruption, often manifesting as a perceived infiltration or occupation of their own mind or body by an alien consciousness, an altered version of themselves, or an external force. This is not a recognized psychological or medical condition but a trope explored in speculative fiction, particularly science fiction and horror.

The narrative device of selfinvasion typically involves themes of identity loss, paranoia, and the uncanny. Characters undergoing selfinvasion may exhibit behaviors that are subtly or overtly out of character, possess memories or knowledge they shouldn't have, or feel a distinct separation from their own actions and thoughts. The source of the invasion can vary, ranging from parasitic organisms to advanced technological manipulation or even supernatural entities.

The psychological impact on the character is central to the exploration of selfinvasion. It often raises questions about the nature of consciousness, free will, and what constitutes the self. The ambiguity of whether the invasion is real or a manifestation of a psychological breakdown adds to the tension and suspense in fictional narratives. Unlike a possession narrative where an external entity takes control, selfinvasion often implies a more insidious and less clearly defined alteration of the original self, blurring the lines between the host and the invader.
