The expression "be lost to the world" means that someone is completely absorbed or detached from reality, and not paying attention to what is happening around them. It can be used to describe someone who is daydreaming, deep in thought or completely immersed in a task or activity. This expression can be used in both positive and negative contexts. For example, one could say "I was lost to the world while reading my favorite book", which means they were so engrossed in the book that they lost track of time and their surroundings. On the other hand, it could be used negatively to describe someone who is ignoring their responsibilities or neglecting their duties, like "John was lost to the world and forgot about his appointment".
