Something interesting actually happened recently when I visited my parents house this year on xmas eve. Their house is very old (neighbours live not very close) and located on the countryside. We all sat in the living room in the evening watching TV, when suddenly all of us heard a big thump (like someone made a heavy jump on the the floor above us). We all looked up in the ceiling at the same direction were we heard the sound and then we discovered that one of the many candles in the hanging candelabra was not burning right. My mother went up to put out the flame and then afterwards something that sounded like few steps on the floor above us could be heard (as if someone was pleased with us quickly reacting to the fire hazard & therefore walked away). My mother don't believe in spirits, the paranormal or ghosts so we said it was probably just the wind shaking the house.
And speaking of fire. This year I received this as a gift.
