Have you met the Goblin Witch while exploring the outskirts yet? If not, click Explore and keep entering random directions until you don't get a scene, then pay attention to the text clues the game gives you - they'll indicate the direction you need to go to find her. After that, keep following the Goblin Witch's storyline until she tells you her name. Then you can talk to Chloe in her room in the morning and continue her storyline.
Oh, and it sounds obvious, but sometimes people get confused - make sure you're exploring the map with the farm on it, and not the Town or the Mountains :)
Hope that helps!
