It seems as if I slept a few minutes ago , had an eventful dream and then was impolitely woken up . That 's how these 11 weeks at Redmond have whooshed past . And at this point , it 's still unclear to me how so many experiences and so many memories were registered in a single summer .

Question: What is the reason that it was unclear about there being so many memories in a summer ?
Answer: None of the above choices .The summer was so exciting it seems like I lived a lot during the summer months .I was so tightly packed that I forgot .My clothes were packed in tight cases and it was disconcerting .
