The expression "have your nose in something" means to be deeply involved in or engrossed in something, such as a book or a project. It can be used in various situations where someone is intensely focused on something and is not paying attention to anything else. For example, "She had her nose in her book all day and didn't even notice when her friends came over." It is a figurative expression, and does not actually mean physically putting your nose in something.
