Your dream seems to reflect a blend of intellect, curiosity, and a desire to hold onto knowledge, especially in a time of transition or change, as you are in your teenage years. Here are some interpretations of the key elements in your dream:

1. Books in the Kitchen: The kitchen often symbolizes nourishment and personal growth. Having books there could suggest that you are seeking intellectual nourishment or that knowledge is a crucial part of your personal development at this stage in your life.
2. Thin Book on General Relativity: This specific book might represent your interest or contemplation of complex ideas and theories. The fact that it’s thin and contains problems could imply that you are at a point where you're beginning to grapple with difficult concepts and are eager to understand them, even if they seem challenging.
3. Family Wanting to Throw It Out: This could symbolize the conflict between your desire for knowledge and the more practical or conventional views of those around you. It might reflect a fear of losing valuable insights or aspects of your identity as you grow older.
4. Thick Narrative Books: These might represent the more traditional or emotional aspects of life, contrasting with your intellectual pursuits. They could signify the balance between learning from stories and experiences versus seeking out factual or theoretical knowledge.
5. Wikipedia Page and Particles: This part of the dream might indicate your fascination with science and the quest for understanding the universe. The mention of particles and wavefunctions suggests you might be wrestling with abstract concepts and trying to find your place in the broader context of knowledge.

Overall, your dream could be encouraging you to embrace your curiosity and the pursuit of knowledge, while also balancing it with the emotional and narrative aspects of life. It might be a good time to explore your interests further, whether in science or other subjects that intrigue you, and to communicate with your family about why these interests are important to you.
