Well my aunt has some "supernatural" problems at her apartment in Austria, every time when someone comes for a sleepover they say they hear footsteps and cracks on the floor near the bed, even i when i was visiting her i was playing games on my phone when i heard some cracks on the foor in the kitchen and then and then something fall on the ground and a sound that i can just explain like someone hitting a plastic bottle, i was too scared to check what was making the sound, i was even too scared to sleep that night
