Dream dictionary: perspire dream meanings
If you dream of being in a place that is extremely hot, or if the weather is so hot that the heat affects you, it shows that some person is preparing either to attack you or give you a good scolding; if you perspire freely, it is a sign you will meet them at advantage, but if you are feverish, it shows that you will be either injured, or else will have your feelings badly hurt.
