Alligators with Wings

Long dream of which I remember very little. I am on land looking out on the horizon toward an island. I decide to go there. It is part of my mission. I set off for the island, am almost there, look up into the sky to see a swarm. They are alligators with wings and they are coming toward me. I feel a slight sense of panic - there are dozens of them. But I have to reach the island.
