Certain Dialogue

One of the issues with Lovecraft is his lack of template for dialogue. Narration usually drives the story forward. It's likely due to being such an introvert that he didn't know how his characters should speak. This is rarely a detriment as his stories are so good that it's hard to hold the flaws in a larger light. But this still leaves today writer's with the question of how to write dialogue for a Lovecraftian world. Stephen King has written such stories but the dialogue remains in his own format. Stories such as "N." or "Revival" have Eldritch elements but lack dialogue that would accompany anything but a King story. Other authors have tried similar approaches to Eldritch world dialogue but what do you talk about when everything is futile? The characters usually come to that conclusion through their adventures and are left off for the worse. It's like trying to get someone at a funeral to talk, it's rude and feels awkward.
