Dreaming about someone over and over

I have a friend who lives far from me. I dream about them that they need my prayers. I usually try to connect with them after the dream to find out what could be happening and why the dream of them telling me to pray for them. We face time and the worst that has happened is an injury on the leg. After the face time, I am at peace and happy but if I stay for long again I start getting disturbing dreams. I have tried to really think but I don’t understand why because there’s no tangible problem. We can FaceTime for up to 2 hours. The injury got healed. I love the person and I am thinking there’s a danger that is coming. I get dreams when someone I love is about to go through something. They are not so spiritual so telling them to pray won’t help.
