Answer:
Presumably unreliable
Step-by-step explanation:
Our eyes often play tricks on the mind; replaying a subconscious memory will change if it's unclear. Psychological studies have shown that memories are unreliable, and small details often change. Even reading something to a few individuals, their summaries will differ depending on their perspectives. Or having people repeat a few spoken sentences from a few minutes ago, they may have been worded differently because what we recall is distinct.
