Something On The Roof

This is my first post here so please forgive for my gramatical errors if any.

So honestly this is my father's experience. This happened when my father was in his teenage. He used to live in Vadodra with his two elder brothers and my grandma. My father used to live in old style houses have rooftops made up of steel and the house was of 3 storeys. My father used to sleep at top most floor while my grandma and uncles used to sleep on 1st and 2nd floor respectively. My dad's room had a balcony which was so small that one can just sleep or crouch underneath (you cannot stand in there).

So one night it was raining heavily. Due to this as of steel roofs sound my father was unable to sleep. At last he had just fallen asleep for about 15 minutes and his sleep was broken with a heavy sound coming from the roof. It was clearly sound of someones footsteps. After some 2 or 3 minutes it stopped. My father ignored it as if it would be any monkey or any animal. He again went to sleep but this time again heared the footsteps and again it stopped but this time my father spotted someone peeping from that balcony. It was just like a human figure with long hairs. Being shocked my father shouted '' who 's there?'' without any reply the creature pulled his head. My father quickly stood up and ran towards the balcony, crouched inside it. To his suprise there was nobody. Next day he narrated the incident to my grandma. She dissmissed it as it would be a thief, but how can a thief climb a 3 storeys building... At that time (with no such instruments) !?

Your thoughts truely welcomed.
