What does a dream of someone tearing pages from a book that belongs to you mean?

Answer 1

This sounds as if there are events in your memory that you would like to destroy. The "someone" in your dream represents some part of yourself. The book contains your memories. It seems that you are ashamed of some behavior or that you would like to eliminate something from your past. An alternate interpretation could be that it is an expression of anxiety, and that you are worried that you might somehow lose your memories, perhaps through amnesia or dementia.
