Light, heat, air
Sounds like a chapter out of worst case scenario - stuck in a moldy room but can't leave - what can you do? Open the windows to dilute out the mold-filled air with fresh air. Leave a light on in the closet with door closed to dry out the closet.
Turn heat up in room to dry out room. If stuck there many days clean walls with diluted bleach or lysol spray. Pull furniture & drapes away from walls.
