Complex and Complexity

By Complex, I refer to the complex that could be verified by experiment, of the type first suggested by Freud, then Carl Jung and others. This thought I just come up today: Complex is formed in relationship with event that elicit strong emotional reaction to the subject, could complex be formed by the nature of complexity of the emotional reactions, or the nature of the incident itself? What I mean by complexity is that when the complexity is below certain threshold, just like the inorganic structure which can’t sustain itself for long, and dissipate as a simple energy structure; while the complexity is above certain threshold, just like the organic structure which is built for self-sustainability, could maintain itself in the psyche much like life in the Physical world.
i.e. Complex is formed because of the nature of complexity of the emotional reactions, which we can apply the theory of complexity from Physics to Psychology.
