This one’s a classic as far as my childhood’s concerned. Its name is a reference to the Alice in Wonderland sequel “Through the Looking-Glass”, and it quickly becomes apparent why such a reference would be made. Dream Mickey steps through his bedroom mirror into a strange mirror image of that bedroom, where furniture and cards are alive, and often willing to dance. This cartoon, generally, would actually fit in quite well with Mickey’s earlier endeavors, thanks to the light plot and surplus of dancing. But what makes this one so much better than what came before is the framing of it as a dream, making Mickey’s waking world not the odd one, as was the case in those older cartoons, but the dream world he enters, instead. It’s also just super imaginative, particularly when the cards come into play. And once Mickey enrages the King of Hearts by dancing with the Queen, things get ridiculous as an army of cards attempts to make Mickey pay. It’s a tragedy that this is Mickey’s last solo venture, and one of the last ones where he stars as the main character, but at least we’ll always have this amazing cartoon.
