Vomiting is read as getting rid of something you could not stomach — an experience, a word, a feeling held down too long. Tradition often treats it as cleansing, the body throwing out what does not belong. Vomiting in public is linked to fear of embarrassment or of losing control in front of others. Someone else vomiting points to their distress or to a situation that has made others uneasy. Feeling sick but unable to vomit is read as tension that cannot yet be released. The dream may ask what in your days has been hard to digest.
