"In this strange situation, my restless imagination entered upon an occupation which saved me from myself and calmed my growing sensuality. This consisted in feeding myself upon the situations which had interested me in the course of my reading, in recalling them, in varying them, in combining them, in making them so truly my own that I became one of the persons who filled my imagination, and always saw myself in the situations most agreeable to my taste; and that, finally, the fictitious state in which I succeeded in putting myself made me forget my actual state with which I was so dissatisfied. This love of imaginary objects, and the readiness with which I occupied myself with them, ended by disgusting me with everything around me, and decided that liking for solitude which has never left me."
