Unless your bedroom is very hot or cold or you have too many or too few bedclothes, perceptions of being or feeling hot or cold in a dream are associated with your emotions. For instance, a refrigerator, freezer or cooler in your dream may indicate emotional coldness or even sexual frigidity in waking life; if you subsequently have dreams of thawing out or defrosting, this indicates that your feelings are changing and your attitudes and emotions are becoming more relaxed. You may even have put something on ice in waking life and feel you can’t make any more progress with it.
On the other hand, feelings of heat or warmth suggest passion for something in your waking life, or feelings of a sexual or loving nature towards someone. Remember, too, that heat is associated with fire and ice is associated with water. Dreams of a romantic sunrise or sunset may contain elements of wish-fulfillment, but they may also suggest feelings of inner optimism if it is a sunrise, and inner contentment with a sense of finality if it is a sunset....
