You and your roommate are discussing your early childhoods and your first day of preschool. She is frustrated because she cannot remember anything related to that first day. She remembers stories that her parents told her about her first days of school because it was right at the time of the events of 9/11, but she does not actually remember the events herself. You would tell her that the inability to remember significant events before the ages of 4 or 5 is common and refers to a loss of memory.

Autobiographical Memory.

Explanation:

The memory that contains the events of our life is the autobiographical memory. This type of memory begins to develop in early childhood, approximately 3 years old. It is usually difficult to retrieve and present in a fragmented form. This is due to the lower neurological maturation during childhood.

Some of the memories present in early childhood are usually implanted memories, that is, it is the memories of someone else. For example, in this case, she doesn't remember her first day of class, the only thing she remembers is what her parents tell her about that day.
