when i was moving out of my apartment into my girlfriends , it was around 9 pm and finishing last of stuff up . we were moving my bed and put mattress down the hallway from my room . all the lights in my apartment were turned on and so we were playing pink floyd on stereo . we went outside to tie box spring to my car and was gone for 15 minutes . when we came back , my mattress somehow moved 6 ft down the hallway and was blocking my door where inside my room only a single lamp in entire apartment was on . all the lights in apartment were turned off except for this one and pink floyd wasn ' t playing , but instead it was just static which i could understand if we were listening to the radio , but my phone was hooked up to it . my girlfriend was too terrified to come inside so i just grabbed my wallet , phone , went to breaker to kill the power and got the hell out of there . i came back next day to retrieve last of stuff and have never been back since .
