Hotel's Toilet

I went to hotel ABC (not real name) at Geylang (name of a place)
with my girlfriend. We wanted to spent some sweet time together.
 At night around four, i heard noise coming from the toilet. I thought
it was my girlfriend but when i turned over, she was beside me.
She wasn’t asleep. She was looking at me. She said she’s scared.
It sounded like a scratching sound like someone trying to cut through
a wooden door or something.I thought it was some pervert around
, trying to sneak up the air con or something. We went to the toilet
and opened. When we switch on the light, we heard a loud thump. We
 looked up and saw that the ceiling was scratched. It doesn’t look like
 any writing. But there were powder on the floor. Someone was there
and it was scratching on the ceilings. We watch HBO trying to distract
 our mind.
