A hug is a very pleasant dream symbol. It suggests love and tenderness and is a symbol of comfort and protection. The only time that this dream symbol has negative connotations is if you were to hug or be hugged by a very negative person or something that you consider "evil." Otherwise, it is a sweet and comforting dream symbol.
To dream that you are hugging someone symbolizes your loving and caring nature. You are holding someone or something close to your heart. Also, it may indicate your need to be more affectionate.
