My room is the entire upper floor or should i say attic, where i could partially see the outside door from my bed. It was summer break and i had gone to bed at around 1AM after browsing Reddit/watching YouTube and tried my hardest to fall asleep. I can't remember if i fell asleep or not, but at around 2AM i had to go take a piss and i started hearing this hollow type whistling sound. It sounded like it was made by a human and all i could hear was that sound wandering around the corridors, everything else was absolutely silent. Now, living in Finland, where the sun stays up 24 hours during the summer, it wasn't dark in the house and because of that i wasn't scared at all. I just thought it was one of my parents wandering to the bathroom and back.

After the whistling sound ended, i figured the bathroom was unoccupied and went downstairs. On the last steps of the staircase i noticed something odd. The outside door was slightly opened. Now this really creeped me out, because our two german shepherds would've absolutely exploded barking if someone opened the door at 2AM. I went and closed the door and as i was closing the door, i could feel a small gush of wind blowing through the doorway from the inside to the outside, causing minor resistance in closing the door. After shutting the door as silently as possible so our GSDs wouldn't start their intruder alert, i went to the bathroom and back to my bed. Needless to say i took one of our dogs with me.
