Dreams are not really meant to scare us away or mean that it must happen the way we see it in our dreams. Some dreams comes as warning or for us to take precautions to prevent that dream from coming to pass. It might be spiritual actions just like you prayed after waking up which I believe averted that death off and there are physical actions like getting to ensure your dad gets treated well enough because of the fear of the dream you had.

So dreams are not compulsorily meant to pass the way we are shown if measures are taken to avert it
