For some nights I slept profoundly; but still every morning I felt the same lassitude, and a languor weighed upon me all day. I felt myself a changed girl. A strange melancholy was stealing over me, a melancholy that I would not have interrupted. Dim thoughts of death began to open, and an idea that I was slowly sinking took gentle, and, somehow, not unwelcome possession of me. If it was sad, the tone of mind which this induced was also sweet. Whatever it might be, my soul acquiesced in it.
J. Sheridan Le Fanu, Carmilla
