Wow, my daughter says things like your son does as well! The other day she refused to go in the front room because she was scared of the "piggy" in there! She runs to me every time she hears the front door open even when I tell her it's daddy. Any noise out of the ordinary she will ask "what was THAT!" She's only seen sesame street, so it's not like she's exposed to anything scary at all. But even today we were outside and I noticed a couple hornets in the grass in the corner of our yard and mentioned to DH that I don't want Olivia walking barefoot in the grass. About 5 min. later she was mad because her shoe fell off and I told her it's okay to take them off. She said "I scared of the bees mommy" I didn't realize just how well she listens to me!
