When you dream of an alligator, it could hold a different latent meaning. For instance, during waking life, you may know a person who shows traits similar to an alligator. This person may have a sharp mouth spitting destructive criticisms, on the sly. Just like the reptile who hunts by catching prey unawares, the person who resembles an alligator behaves similarly. The person need not physically resemble the features of an alligator.
