The possessed.

"Stephen there's something wrong with the lights come and help me check it" my girlfriend said as i left the basement to join her. It seemed very unusual because we never had any issue with the electricity when suddenly i tried checking with the lights and we notice a girl by the corner of the room in a dirty white dress bowing her head and suddenly she disappears when the light went off and on. 

We thought it was from the horror movie we saw recently that got us illucinating when suddenly the door slammed and shut closed this time i was getting scared as i jumped off the stool and ran towards the door to open it but it was closed and my girlfriend started panicking and as i tried calming her the girl appears again but this time in another corner and I started panking too i didn't know what to do then i notice a baseball bat laying around in the room and held it tight ready to hit the girl when suddenly she appears again closer to me, as i swung the bat she pulled my girlfriend to the location and had me swinging at her and hitting her breaking her neck. My girlfriend fell down lifelessly as i think she passed out from that and left me more scared. i began to panic when suddenly the lights went off totally and there was no sign of the girl in the white dress until after a minute the lights went back on but this time my girlfriend was at the corner smiling with her eyes black and blood on her clothes from me hitting her.

"don't be scared, I won't hurt you" she said in a possessed voice as my legs began to shake and i couldn't move my arms, she ran towards me too fast i couldn't escape and held my neck to the wall lifting me off the ground. My heart started beating faster as i looked in her eyes and saw total darkness and as she swung me through the window of the house letting me see my myself end.
