Spindle activity appears to be particularly important for overnight integration of new memories with existing neocortical knowledge, and was associated with overnight lexical integration in the sleep group, but not with gains in recall rate or recognition speed of the novel words themselves.
Human relational memory requires time and sleep

It is demonstrated that human relational memory develops during offline time delays, and sleep appears to preferentially facilitate this process by enhancing hierarchical memory binding, thereby allowing superior performance for the more distant inferential judgments, a benefit that may operate below the level of conscious awareness.
Sleep Preferentially Enhances Memory for Emotional Components of Scenes

Investigation of the evolution of memory for negative scenes across 30 min, 12 daytime hours spent awake, and 12 nighttime hours including sleep suggests that the two components undergo differential processing during sleep.
Stress administered prior to encoding impairs neutral but enhances emotional long-term episodic memories.

It is demonstrated that stress, when administered prior to encoding, produces different patterns of long-term remembering for neutral and emotional episodes, and these differences likely emerge from differential actions of stress hormones on memory-relevant regions of the brain.
The role of sleep in false memory formation
Stress Differentially Modulates Fear Conditioning in Healthy Men and Women
The effects of experimentally induced stress on false recognition
The impact of experimentally induced stress on the ability of human participants to accurately recognise words presented on a list was found to be selective, indicating that stress, possibly through its impact on the hippocampus and prefrontal cortex, can potentiate false memories.
Sleep, dreams, and memory consolidation: the role of the stress hormone cortisol.
The relationship between sleep, dreams, and memory, and the hormone cortisol is discussed, proposing that the content of dreams reflects aspects of memory consolidation taking place during the different stages of sleep.
