Evidence suggests that we consolidate our memories of recent life events through

A) sleeptalking.
B) EEG recordings.
C) sleep apnea.
D) REM sleep.

Studies have shown that we consolidate memories during REM (Rapid Eye Movement) sleep, which is a phase of sleep where we typically dream. During this stage, our brains are busy processing and consolidating memories from the day before, which helps to strengthen and store them in our long-term memory. Therefore, the best choice is D, REM sleep. The other options, such as sleeptalking, EEG recordings, and sleep apnea, are not directly related to memory consolidation.
