of course, "normal way of life disturbed" is also a possibility!

This is the way I always see it in the books on psychoanalysis that I read just about every day of the year.

Generally agreed, in psychology and psychiatry, the instincts
- therefore instinctual life- is different from affect, emotions and life outlook, perspective or believes or attitudes.

In psychoanalytic theory, in general, the two main instincts are life (libido) and death (thanatos). Instinctual life will refer to the particular "combination" and expression of these two instincts along one's history. They rule our cognitive and emotional life as well as our behavior.

In cognitive and behavioristic psychology, instinctual life is also different from affect or behavior per se. Instincts (sometimes called drives) could be considered as the basic motivation of behavior, thought and emotion and comprise elements sucha as hunger, sleep, sex, agression.

So, in general,in psychological jargon (clinical notes or histories), instinctual life is a specific term and is assesed separately from other aspects. There are plenty of links where one could review the subject, from different theoretical perspectives.

My answer is not a separate answer. It intends to be an explanatory comment, to support Deborah's answer.

Regarding the use of "instinctual life" in classic and modern psychoanalytic theory: See, among many examples,

http://www.cmps.edu/psychoanalytic/courses.html
"Maturation courses investigate knowledge of normal and pathological development, as well as theories of regression, and relate cases to stages in the developmental process. Neurophysiological sequences are related to the vicissitudes of instinctual life as they affect emotional development".

"...it became clear that these tensions were also reflections of the expectable theoretical tensions between the ego and the id, the social and the biological, rational life and instinctual life, moral life and sexual life--tensions peculiar to and expressive of the richness of the psychoanalytic vision of the human mind. I know that it will be occurring to the reader that the classification--social, rational, moral, ego on the one side with the biological, instinctual, sexual, id on the other--while capturing something important about the way we think of the mental life, also overlooks other matters equally crucial to development and experience. These days, in theory at least, we always keep in mind the mutual influences of ego and id".

Excerpt from Civilization & Its Discontents: "With regard to the primitive human types living at the present time, careful investigation has revealed that their instinctual life is by no means to be ..."
