In rapid eye movement (REM) period of sleep, the discharges sent by the pontine reticular formation, stimulating pools of the memories in the neocortex and other memory storage areas of the brain, constitute the dream scenarios. If the neuronal connections of memories establish random synaptic relationships with each other, it can be concluded that recently-activated neurons can randomly stimulate the neurons of other memories converging on them. For example increasing activities in the memory neurons belonged to Grandmother and an unrelated war scene may constitute a dream scenario by random connections as a grandmother with weapon without subject integrity.
