I think I hear footsteps outside?

It's 1:30am and everyone in my house is sleeping and I was sitting in bed getting ready to sleep when I heard shuffling outside. It sounds like someone's walking around crunching leaves and breaking sticks, but it's dark so I can't see anything. So I was looking out my window to see if it was just an animal when I saw 2 really bright flashes that looked like an iPhone camera taking a picture, and I assumed it was lightning but I waited and didn't hear any thunder and checked the weather reports and there's not suppose to be any and the skies clear. I don't know what to do I can hardly type because I'm on the verge of a panic attack and I'm so scared should I wake my parents up?!

Ok i'll take my shoes off
