Did you ever see the movie Home Alone?  The movie scared me as a child
I saw it when I was much older but my parents didn't let me watch it when I was young.  I bet.  That wouldn't be like real life for really being left home alone. 
I was terrified to go into my basement after I saw that movie.  The furnace was so scary
I forgot about that part!  Yes!  Terrifying!  Hope you didn't have too many nightmares over it.
