Could I to get sicker because I breathed in mold?

Yes. Not all molds are pathogenic, but if you are suceptible or allergic person your chances to developed a reaction to it are higher. Best to clean with diluted white vinegar & aerated better the room.
Clean/Bleach. Mold commonly grows in moist environments. Individuals who are prone to allergic responses or who are exposed to high levels of mold may have a variety of illness and complaints associated. Keeping the air dry by use of a de-humidifier and cleaning with a dilute bleach solution may help to decrease your exposure. I hope this helps.
