A biography is to give account of events and significant moments and academic achievements of a person. An autobiography, instead of being written by a different author, is an own record of a life story written by the same author. A predominant characteristic of an autobiography is that it is written in the first-person point of view, accordingly the author has access to his or her own experiences and thoughts. It is important to add that the narration of events takes place in the first person mode.
When the narrator is saying this, he cannot see if their is anything else around him, because it is too dark to see. But the darkness is all around him, so the statement is true in a way.
