So, this dream has 2 main parts, but I don't remember much about either of them.
Part 1 is where I took seven new courses simultaneously (and at my university, the typical number of simultaneous courses is like 3). I don't remember much about it except that I had to take classes in a school building that was not my university because dream logic.
And part 2 was about YouTubers wearing outfits to certain occasions. I don't remember much about it except that T-Series' outfits for every occasion were a suit and a pumpkin dress. (Looked up Tomodachi Life images for references to which clothes look the closest to the ones in my dream.)
