Unsymbolized thinking.

Unsymbolized thinking--the experience of an explicit, differentiated thought that does not include the experience of words, images, or any other symbols--is a frequently occurring yet little known phenomenon. Unsymbolized thinking is a distinct phenomenon, not merely, for example, an incompletely formed inner speech or a vague image, and is one of the five most common features of inner experience (the other four: inner speech, inner seeing, feelings, and sensory awareness). Despite its high frequency, many people, including many professional students of consciousness, believe that such an experience is impossible.
