This title is on horror based story which I have experienced

This is a story of myself when I was 11 years old. Our family was living in police provided quarters. Electricity was gone for 2-3 days. Each member of our building decided to shift their cooking things n gas cylinders to cook food on the roof of the building. My mom's was also on the roof,and suddenly she said baby go down to our quarter and bring the rice cleaning utensil ..I said ok and when I entered my room someone was under the bed and pulled my leg ..at that time I got frightened and I started shouting ...each member of our building came their and said what happened I said someone is under the bed and he pulled my leg ...2-3 members started searching that who had pulled my leg..but they found nothing there ..even today also I'm always thinking that who was under the bed
