Something Spooky!!!

So, about 3 weeks ago i had my graduation party. the next day was my grandpas birthday party. when we got home at like 9:30 pm i decided i wanted to go to the basement and get a popsicle. after i grabed the popcicle i noticed the light was on in the basement bathroom. i thought some one left it on from my grad party the night before. when i went over the door (which is a sliding door) was opened a crack and i heard scratching noices coming from inside the bathroom. i convinced my self it was my stepdad so i went up and never checked. when i went up i found out my stepdad was outside walking the dog and my mom was asleep!!! i woke my mom up and we both went down stairs to check it out ( i may have been carying something sharp ^_^). when we got downstairs to the basement the bathroom light was off and the door was wide open!!!!!!!!!! thats what freaked me out b/c when i first saw it the light was on & the door was closed! now the light was off and the doo was WIDE OPEN! lets just say i may have slept with a knife by my side that night.
