Spooky

Was alone at home last night. At about 11++, I was in the toilet making some nice chocolate cakes. It was quiet at that moment except the sound of that cake making process. All of a sudden, I heard sound from the door of the toilet as if the door was attempted to be pushed a few times from outside. F*ckkk! It did not sound like the power of the wind. It happened for about 3 to 4 times in 5 seconds. That was not the first time. Few days ago, I heard some weird sounds in my room!! Was I too tired?? Or something actually.. :S
