This didn't happen to me, but one of my mum's best mates daughter. Tthis happened in Cygnet, Tasmania (Australia). This girl (Jenny) was in bed one night and heard these noises out in the lounge-room, so Jenny went out to have a look but there was nothing there. She lived with only her mum, but her mum was still sound asleep in bed.
The next few nights, the same thing was happening, but still nobody there. Jenny told her mum, but her mum thought she was just imagining it.
So that night before she went to bed, Jenny got out a box of cornflakes and a bag of flour, she spread them all over the lounge room where she was hearing the noises. As she was laying in bed, she heard a crunch, crunch (the cornflakes).
She was to scared to go out and check so she waited until morning. When she walked out, the cornflakes were all broken up, there was footprints (bare feet) printed in the in the flour. The strange thing was the footprints started in the middle of the room and ended in the middle of the room. There was no way these footprints could be her or her mum because they didn't start or end anywhere.
After that the noises stopped and everything went back to normal, but she still has nightmares about it now.
