MORNING WOOOORLD =D

anyways last night i was really tired at like 230am or something, so i decided to crash but there was this weird ass sound coming from the basement and it was annoying the shit outta me. so i went down to the basement, and i didnt see anything there and the sound went away; so i went back tomy room and 2 minutes later...~knock knock knock knock~, well idk how to explain this sound, anyways i was getting really mad so i went down there again and i looked around a bit more. the window down there was open so i closed it and went back to my room. i was abt to fall asleep then...~knock knock knock knock knock~ i was super pissed off at this point, so i figured it might have been my douche bag step brother playing tricks on me...but that wouldnt be possible since he decided to sleep-over at a friends house, anyways i went back downstairs and THE WINDOW WAS OPEN AGAIN! so i started gettin kinda creeped out, i just closed the window again, LOCKED IT and went back to my room, but the knocking sound started again, and when i went to check the window was wide open and it was unlocked. i went to close the window and i decided to put this...vase like thingy near the window to see if it would move. surely enough the knocking sound starts again so i go to the basement again and the window is open, vase is back on the shelf where it came from. =.= so i was pretty scared at this point so i close the window and call my friend and told her wut was happening and shit. she told me to turn the light closest to the window on and see if the same thing happens. this seemed pretty stupid to me, but i was outta ideas so i tried it, went back to my room and....~knock knock knock knock~. when i went down there....light off, light bulb shattered on the floor and the window WIDE OPEN. i was shitting bricks at this point so i just went to bed and tried not to let the knocking shit disturb me T.T NEVER GOING IN MY BASEMENT EVER AGAIN!!!!
