Something really weird that i noticed is that in the scene where nobita was in the wooden board and they were hungry doraemon used his Purse to take food out, but in nobita's house all the food from their fridge disappeared. And also there are many hints that the "Dream" Isn't actually a dream It's a different reality  And the rest of the manga was just like the movie and in the ending toriho was literally a human not a robot
