What is most likely the implication of these lines

B. The events may have occurred in a dream.

Explanation:

In these lines, Dante tells us that before he entered the path he will tell us about, he had grown drowsy with sleep. This means that he felt really sleepy right before this journey started. Moreover, he tells us that he does not remember how he entered the path. What all this is meant to imply is the fact that the events Dante will describe might have been part of a dream, and not a true story.
