As a child I was convinced that the furnace only came on when someone walked past a certain point in the house (namely the entrance to my bedroom hallway). When I heard it come on at night I was sure that it was ghosts or someone else in the house.
A childhood belief about around the house

- I used to believe that when we went to bed at night, all the animals in our house talked to each other. Anon
- I used to believe that if you opened up an umbrella inside your house that the whole house would fly awayAnon
- As a kid, I thought "No Outlet" signs meant the houses past that point didn't have any electrical outlets.— Julie
