Dreams involving books often symbolize knowledge, learning, or the desire for deeper understanding. The act of reading in your dream suggests you may be seeking insights or answers to questions in your life. However, the boiling hot black tar that oozed out can represent something unsettling or toxic, possibly indicating that there are aspects of your life or emotions that you are not fully aware of or are trying to ignore.

The sensation of the tar falling into your eyes and waking up in shock could signify a fear of being confronted with harsh truths or realities that you find difficult to face. Rubbing your eyes might suggest a desire to clear your vision or to gain clarity in a situation that feels overwhelming.

Consider reflecting on any current challenges or feelings of discomfort you might be experiencing. This dream could be urging you to confront these issues instead of avoiding them. Engaging with difficult emotions or truths may ultimately lead to personal growth and understanding.
