This is really kind of scary for a parent to deal with. Especially when the child is unable to say exactly what is worrying him. He's probably just got an overactive imagination. A lot of kids that age do. My son is 2 1/2 and worries about "dragons" in his room. A few times I heard him crying after I put him to bed so I want and asked him what was wrong and he said he was too scared to sleep because of the dragons. I have managed to convince him that the dragons are scared of his teddy bears, and things have been a lot better. All you can do is assure your son that you are there to look after him and that, whatever it is he's seeing, you won't let it hurt him.
