Little shadow!?!?

I am so sorry for all the preguntas but I am somewhat panicking and didn't know where else to go.

So I woke up in the middle of the night, I was laying in cama and I swear I saw a shadow of a small boy come off my deck and hide behind the curtains... but this was a very small shadow. It looked like it wasn't even quite 4 feet tall. I was also TERRIFIED. I was frozen in terror for a good minuto o too with my corazón beating so fast I thought it was going to explode. What the heck was that? I know I saw it! If it helps at all, earlier that night I saw a larger shadow of a boy that I am pretty sure was Peter fly from my backyard to the roof while I was singing.
