Question: What does the word awake mean in describing a person?
Answer: When describing someone as awake, they usually mean to say that you're 'an alert and aware' person. To further evaluate, your senses are truly heightened and nothing can get past you. Depending on the context, this could be a compliment or an insult; probably best to see to it as a compliment.
