Is it a story?

I'd been thinking about writing a little story, and I decided to do it in English.

The house was empty but I could see that someone had been there and had only just left. I didn't really know what to do, if I had to call the police, my parents or who. 

Suddenly, I ran out of my house and I walked to my grandmother's house. When I arrived there, I realized that the same thing had happened there; everything had been moved to another placee. I tiptoed to my grandma's bedroom and she was completely asleep. To my surprise, all the lights were switched on, and then I called my mother. 

I was starting to get afraid because she wasn't answering my call. I went back to my house and when I opened the door, everything was in perfect order, in their places. At that moment I was freaking out because of that situation, and nobody appeared until the next day.

All this happened three days ago, and I still don't know what took place in my house.
