Final answer:
Surrealism is the artistic style characterized by impersonal and spontaneous depictions of subjects, influenced by the subconscious and dream analysis, challenging the boundaries of reality.
Step-by-step explanation:
The artistic style that features impersonal depictions of characters compelled to behave in ways over which they have no control is Surrealism. This movement was highly influenced by the writings of Sigmund Freud and expressed the subconscious mind through strange and dreamlike images and scenarios. Surrealism allowed for the spontaneous and automatic creation of art, often based upon dreams or the unconscious mind, overcoming the constraints of rational thought and societal norms. Works of Surrealist art present viewers with scenes that blur the boundaries between reality and dreams, encouraging a deeper exploration into the psyche.
