I read a book directed at children, in the early 2000s. It was a sort of collection of short stories, and there was this one story about this bully. One time he tried to rob a lady at a bus stop, and said the words "give it to me" at which point she threw something invisible at him, which he caught. It was jelly like, and I believe he felt it dripping down his hands.
Following that moment, he had dreams (involving snakes, I believe they were described as very very long snakes slithering possibly along the border of whatever he was seeing/thinking during the dream. I'm not a hundred percent sure about the snakes, but I'm like 90%) , where he would see what people were thinking of him, causing him to change his ways.
He stopped hanging out with his other bully friends, and I think he himself was bullied by them, and one of them, trying to take his lunch money perhaps, said "give it to me" at which point he passed the invisible jelly-like thing onwards. Does anyone know the name of this collection, or at least of this story?
Some more context: I live in the US, and this book was found in my fourth or fifth grade classroom.
I suddenly seem to remember that the cover had someone with a lot of eyes on it. But I could be mistaken.
