One night when i was about seven or eight i was staying the night over at my grandmothers house. i had gotten up in the middle of the night at around 230 or 300. i cant remember. buyt anyways, i go my water and went back into my bedroom . now in my room, my bed is against the wall that divides my room and my grandmothers room. i was just about to fall asleep when i heard these huge long echoing knocks on the wall where my bed was. i thought it was my grandmothers trying to tell me to go back asleep so i knocked back. three times. and then three times back there was knocking. all of a sudden my grandmother comes bursting in my room asking and yelling about the noise that i was making on her wall.i told her it wasnt me. and she didnt believe me but then again three long echoing knocks on the wall. and again. they got louder and louder. my grandma fell to the floor and started to pray the knocking faded then faded. since then we never hear it anymore.
