The Big Dictionary of Dreams

by Martha Clarke
Dreaming of a stifling heat suggests that you have a lot of energy but you are not using it properly. This dream may indicate a tendency toward aggression and conflict. You despise yourself and tend to externalize your own dissatisfactions against others.

If you burn and have a burning sensation in the dream, it is a sign of lawlessness in your instincts.

Dreams of heat represent passion, sexuality, energy, and power; being engaged in activity that warms your soul. Sometimes heat, like chemistry, happens when opposites attract or have friction. You might also have too many blankets on you as you are sleeping.
