Dream Of Cousins House Chaos Shopping For Books

This dream was about

I remember I had a dream, I was at my cousin's (A boy) house... I'm in my room and it seems like me and my cousin are on a hide and seek..But all I know is, everything was in chaos. Their house is quite spacious and so I was going in and out in their room... My cousin is running here and on.. Then, I remember my aunt and mother taking us shopping. We're allowed to get toys/things we like as long it cost ₱500.. Instead of getting some toys, I got a book. I went to the counter and the sales lady mentioned the books were written by someone named "Edgar Allan Poe" whom I've heard somewhere before. I have two books to choose from, and I get a pink and blue. I chose the blue one. I was enthusiastic about the book and bought it. So, My Mother was intrigued and surprised by what I got. Which is the book. There are things inside the book like a pen perhaps.. but that thing is elegant and old fashioned which interests me even more.. and it caught my mother's interest too. She asked me if she could borrow it I said no.
