Feeling cold in a dream can be seen as either physical or spiritual discomfort. A nightmare that you are trapped in a freezer or you are shivering from the cold winter air might symbolize something literal, like being disregarded or getting blown off by someone chilly.
Dreams about the cold also commonly represents regret, loneliness, shock and sadness. In some cultures, extreme cold typically have negative connotations because it symbolizes struggle and death when it appears in dreams.
