Dream of eyes, grandmother, person

I am a lethal guardian. I was feared by most people and misunderstood. My real form was a black wolf with blood red eyes and black wings. When I was in human form I was able to keep my wings. I had a vision that the world had less than 24 hours before there was a zombie apocalypse. The vision included the people I loved dead and I was leading some people safely on an island. Then I went to an organization that was formed to kill monsters like me and I told them my vision. The worst part was I was crying because the person I like was part of the organization and his grandmother was the one in charge. So eventually I told the guy I like that I wanted him and the organization to go the island that I saw in my vision to be safe. They refused and stayed behind to fight the zombies with me while we were trying to save the human race.
