Well, it could be about a lot of things. Maybe Jacob's Ladder is a movie or a book that claims to be based on real events. It might be about a person named Jacob and his journey or experiences in life that are being told as a true story.
The 'Jacob's Ladder' is often associated with a visionary or spiritual concept. In some religious and cultural beliefs, Jacob's Ladder was a ladder that reached from earth to heaven which Jacob dreamed about in the Bible. It represents a connection between the earthly realm and the divine. This is the core of the true story as per religious texts.
In modern times, the Jacob's Ladder true story can be seen as a psychological concept too. It can represent the steps one takes in self - discovery. For example, the ladder could be the different levels of consciousness that a person explores as they strive to understand themselves better. The angels ascending and descending could symbolize positive and negative thoughts or influences in this journey of self - awareness.
One example could be that Jacob was a soldier in a war. His 'ladder' could represent his journey from the horrors of the battlefield to finding peace after the war. The true story part could be based on real battles, real people he met during the war, and his real struggle to adapt to civilian life again.
