Face in Shadows emoji features a face in a pall or fog. The eyes, eyebrows, lips, and facial features aren't easily visible, indicating confusion, query, and sadness. The presence of fog is a conceit for emotional confusion or internal burden.
The face in shadows emoji is used when a person feels like they're in a fog, as if the path of life is blurred and they can’t see themselves or their destination. This emoji shows disorientation, depression, or emotional prostration. When a person’s mind is clouded, their heart is confused, and there's no stopgap left, this emoji impeccably expresses this state. It's substantially used on social media when someone is experiencing severe internal stress or despair, and it's delicate to express it in words.
