The term "oblivious" specifically describes a state of being completely unaware or lacking conscious awareness of one's surroundings or circumstances. When someone is oblivious, they are often so absorbed in their thoughts or activities that they fail to notice what is happening around them. This term captures the essence of unawareness in a more profound way, suggesting a degree of detachment from the environment.

In contrast, while "mindless" can also imply a lack of awareness, it often connotes a more negative perspective regarding one's actions, suggesting thoughtlessness rather than mere unawareness. The term "unaware" straightforwardly implies not being aware, but it doesn't convey the depth of being completely absorbed or indifferent to the surrounding context as "oblivious" does. Similarly, "negligent" implies a failure to take proper care or notice of something, often in a context where responsibility is expected, making it less about a general state of unawareness and more about a lack of attention that can lead to oversight in duties or responsibilities.

Thus, "oblivious" is the most fitting term, encapsulating the idea of being so unaware of one’s surroundings that one may remain completely ignorant of external factors or circumstances.
