The atmosphere of a dream is important in that it portrays the condition of your 'inner world.' To dream of being cold can indicate how you have 'cooled off' in your emotions or are acting coldly in some situation - whether or not you are aware of it. Since dreams are processing what we are not acknowledging, you might examine how you can bring more 'warmth' into your interactions with others. At the same time, your current environment may seem cold or distant to you. See also Frozen.
