Linda, it is pretty scary, isn't it? It just seems to be the luck of the draw what particular kind of spore takes up residence. Usually places where this is a problem have massive growths, such as houses that have been abandoned for some time. Also, some people are more sensitive to such things than others. In your case, the key is to get things repaired, cleanded up, and dried out before there is a problem. You probably already guessed that, just don't procrastinate.
