Certainly, the heat itself can not dream, but a person can feel it, feel the heat. So, if in a dream you felt a fever, although objectively the source of heat was not nearby - then in real life you will be destined to experience a strong love feeling, which, as you thought, you were not capable of.

If you dreamed that you have a fever, then you are paying too much attention to trifles, missing the most important thing in life. You need to pull yourself together and devote your life to important things. To see in a dream that one of your loved ones has a fever is a mild illness of one of them.
