Shattered dreams

So the other morning Max comes running into my bedroom so excited asking me where his bag of guns and lightsabers are. I try to reason with him for a minute how he doesn't have a bag of guns and lightsabers and then wanting my sleep tell him they are in the toy room. So he goes running into the toy room and then comes back so sad. telling me they are not there and that the man gave them to him and told him they were all his. He went on forever and finally I realized he had had a dream about a man giving him a bag of guns and lightsabers. I told him honey it's just a dream and he was soooo bummed! all day long he kept saying I didn't get my guns mom it was just a dream!
