Dreams or visions about reading tell you that you want insight into a situation beyond your control. Another explanation is the desire for recognition, wealth and status, but also wanting help and support in your loneliness or in a difficult time. You have to pay close attention to what you read in your dream or vision because this is an indication in which you want insight or what you want to achieve, what kind of recognition you want to receive and from whom; maybe yours.
The book reflects your soul, you are the book yourself. You symbolically read your soul pages, your package insert, your description and what obstacles and experiences that come with it.
Another explanation is to experience your calmness, inner peace and balance between your masculine and feminine energy. Another explanation is to find knowledge, interests, intelligence, information and wisdom regarding the past and present, or perhaps to get a glimpse of the still unknown future. Another explanation is that reading wants to make you aware that schooling or taking a course is a good next step in your life, or that writing or reading books is part of your life goal.
