ABSTRACT
This chapter examines many other authorities contend that a definite relationship between sleep-speech and recalled wakeful mentation is demonstrable at least some of the time. Examination of the comments and observations of the clinical, psychological, and serious anecdotal literature on somniloquy permits one to formulate a series of categories expressing degrees of concordance between sleep-speech and associated mentation content. According to most reports in the clinical-anecdotal literature, mentation associated with sleep-utterance is less accessible to wakeful recall when vocalization occurs under the conditions of: high-arousal-threshold sleep, body movement episodes and somnambulistic episodes. Several categories of such relationship may be discerned in comments in the literature concerning sleep-speech content and proximate sleep mentation. B. Fosgate, J. N. Pinkerton, and F. Fischer independently distinguished between two types of sleep-talking, one occurring during “dreaming” sleep and the other during “torpor” or “somnambulic sleep”.
