My encounters

The scream

So, me and my little cousin were walking to my house, since she only lived across the street, we were walking and I could have sworn, I felt like someone, or something, was stalking us.
Now, I'm not positive if this was just a feeling I had, or if my senses were trying to tell me something.
But anyways, we went up to my porch and she stood by the screen door, while I went to get us some water, since it was a hot summer day.
But, when I came back out, she looked as if, someone just jump scared her and she looked up at me, looking even paler, which w as weird since her skin was a tan color.
I asked her what was wrong, and this was our conversation.

"Tessa, what's wrong?"

"Are you okay?"

"What do you mean?"

"I thought you got scared, or were hurt because I heard a scream inside the house!"

This was weird, because I heard nothing inside.
To make it even weirder, no one else was home, and my older sister lived with my auint, and she lived an hour away from me.
But from this day, she still remembers that, and we are still unsure what it was.
