Abstract
Two patients with dreamy state, who had two methods of precipitation and inhibition for the dreamy state, were observed. The methods of inhibition were successful by thinking the other things in both patients. The methods of precipitation were some different by each patient; one patient precipitated dreamy state by recollecting the previous situations of its occurrence, and another patient precipitated it into loss of consciousness by absorbing self into dreamy state. The detailed investigation of our patients and cases from the literatures concluded that dreamy state is divided into emotion, memory and cognition; at first emotion occurs, and then memory and cognition follows. As neurophysiological hypothesis of cortical network, the discharges of amygdala triggers dreamy state and they spread over hippocampus and neocortex.
