Memory amentia describes a psychological phenomenon when the sources of the memory are forgotten. The professors talks about an example of his own experience. One day, when he went to see his sister, he found some butterflies, which reminded of his childhood when he had been hiking with his sister. He said he had been exhausted and would be more likely to give up at the moment. Suddenly, he saw the beautiful butterflies and decided to move on. But his sister laughed at him, because he had mistaken the situation. What the professor described was the childhood memory of a TV program they had once watched together. (107 words)
