What's causing this is a profound lack of housekeeping. Your filth is
sticking to the ceiling by way of hot air flow from the bulbs. As you walk
through the house, sit on your furniture, move things etc. you disturb your
settled filth and it becomes airborne and circulates through your home, gets
trapped in the air circulation and gets stuck to your gummy ceiling. Clean
your house, wash your walls, stop smoking indoors and stop burning your
food!
