How do we know the dream Jacob had was significant?

In Genesis 28, Jacob dreamt of a ladder reaching into heaven with angels ascending and descending on it, which signifies divine communication and God's active engagement with His creation. This isn't a mere ordinary dream but one that carries profound theological weight, illustrating the connection between heaven and earth and foreshadowing the redemptive plan through Christ. The dream underscores God's grace, as Jacob did not merit this revelation; it was purely by God's mercy that he received such a vision.
