unpleasant smell

The dreamed i saw a dead relative, a cat, a bear, a small gray car, a woman. I smell something unpleasant inside my house but can't locate it.

For sometime now the family (###, ###, ###) have been experiencing some unpleasant smell and anytime we inhale we become ill: my ### will have blisters/sour in her mouth while ### and ### will start feeling weak and dizzy.
