Write in a book what you see

When Jesus Christ instructs the apostle John to write, it is apparent that John is awake and able to write. This is in contrast to Daniel who records his dreams and visions (Dan 7:1).

This means that, as John is in "the Spirit of the Lord's Day," he is awake and fully functional to write down events as they occur.
