My whole family and me went to our province in Ilo-Ilo for vacation. We stayed at my grandparent's house, where my mother stayed for 20 years of her life. The house was designed in a western style, very big, with a front and side porch and has a very big beautiful garden at the back. A good place to stay in during vacation. But this vacation went weird and unforgettable.
One night, my older sister went to the kitchen to wash the dishes while my 2 other sisters and I stayed in the living room to chat. After fifteen minutes she went back to the living room and asked us if anyone knocked on the back door. We all said "No". She went back to the kitchen and continued with her task. But after a minute, she went back again and angrily said, "For whoever knocked on that backdoor, please stop it. If I caught any one of you who tried to tease me, I'll make sure mom will know!".
We all looked at her and my oldest sister said: "No one walked outside just to knock you on the back door. We were all here, sitting in one place and we never thought of teasing you or scaring you! If you don't believe us, then, we will accompany you at the kitchen and wait for the knock again!". We all agreed.
We all waited. No one knocked. My sister was done in washing the dishes, we all decided to go to sleep. As we turned off the lights and walked to the hallway towards our bedroom, we heard a KNOCK! We all looked at each other and my oldest sister said, "Who's there?", no one answered. "I said, who's there?", no reply. One of my siblings rushed to my parent's room and woke them up as well as my grandma. During this time, us three were left on the hallway and waiting for the answer but ready to ran as well.
After awhile, my grandma and my father went to check the back door and the garden but there's no sign of human or an animal there. We all went to the living room and explained to my grandma and to my parents what happened. My grandma told us that the house was full of ghosts and many paranormal happenings occurred for the past decades! The house was built before the world war and it was said that throughout the years, the house was never empty with entities...
Our vacation ended with a SPOOK!
