91 / 100
True

The text states that your brain replays some of your memories while you sleep to consolidate them and store them long-term.

Infact verdict: True (91/100).

The claim that the brain replays memories during sleep to consolidate them is supported by scientific evidence. Multiple sources, including research articles and expert blogs, confirm that during sleep, particularly slow-wave sleep, the hippocampus reactivates neural patterns from waking experiences, transferring information to the neocortex for long-term storage. This process is part of the well-established two-stage model of memory consolidation. Therefore, the claim is factual and well-supported by current scientific understanding.
