>>52764101Let me shed some light on Yume culture for you, every Yume has different preferences but generally yeah, there are tropes that appeal to yumes and some common shoujo manga scenarios are often present in most media for Yumes for precisely that reason
Lets start with the basic definition. Yumejoshis are girls who self insert themselves into the female leads in shoujo manga/anime and Otome games. Every single Yume has her preferences and is different. Bae for example has two archetype of characters she has a soft spot for, the sweet prince guy who spoils her but is also a tease at times or the mysterious quiet caring guy, think Itachi from Naruto. Yumes also have their spectrums of degeneracy and kinks which you can make out from what they like in an Otome game
To offer you some perspective into the daily life of a yume, let's use her catboy stream from the other day, the same one IRyS played BUT with a heart monitor so we could see whenever she felt flustered according to her heartrate. At various points in the playthrough, she had her HR risen by all of the catboys but Fennel (ironically the one IRyS liked the most)
Let's break it down route by route
Sage, the big gruffy muscular manly dude. She liked how he was a caring fella who could cook nice meals and he got her up to like a 110HR at points, especially when he offered to cook for her. He sister-zoned her pretty early on though and she was okay and happy with it.
Then comes the climax of the route where he starts indulging in too much skinship in too little time, calling her his girlfriend, little cat and some other shit and this creeps her the fuck out, she becomes dry as fuck and her heart rate falls to like 70-80 for the remainder of the playthrough because it's "incest", it was rather amusing and she desperately wanted to end the route so she could move onto the next
Then there was the white haired Sesshomaru look-alike, Laurier. Due to the Sesshomaru resemblance, his looks alone raised her heartrate and got her acting tsundere, firing her heartrate past 110+ at multiple points with his teasing
Turns out he is a schizo who turns into a grade schooler (mentally) if he eats something too sweet, henceforth is a repeat of the previous route where she is completely turned off and creeped out with a heartrate to match in the 70s by the concept of a child stuck in an adult man's body.
As for her final route of the day, Dill. He was the only character she ended up liking by the end of her stream, he didn't affect her heartrate at all initially since she saw him as a platonic little brother due to his looks and personality but during his route, she started to fall for how nice and sweet he was, got her above a 100 many times as well.
Then comes the twist of his route where it's revealed he's a whore who has fucked many women and he has reverse groomed many girls before, this kind of ruined the character for her a little but he was still a nice dude in general so he remained the favorite albiet little-brother zoned for real. She did not bother giving Fennel a try
Her final ratings at the end of the stream for the characters were as follows
Sage 7/10 pre-incest, 5.5/10 post-incest
Laurier 3/10
Fennel 4.5/10
Dill 8/10 pre-plot twist 7/10 post plot-twist
What we can deduce from this playthrough and the ratings coupled with her heartrate at various points is that her turn offs are Incest, Shotacon and Casanovas. What she likes is someone who is a sweet person who can spoil her and tease her on command and isn't a super degenerate.
Now consider how there are many other Yumejoshis like Bae out there with their own respective set of preferences and kinks. To give some some examples on this, some Yumes are into pet play, the kind where the dude locks them in a cage and you probably know where I'm going with this
There's this dude called Toma from this Otome game called Amnesia with many Yume fans, here is his profile

Now to answer your other questions, about children, yes Bae is very fond of children in general and the death of a child in a videogame drove her to ugly bawling. She was super mad at the mom too
https://youtu.be/xhpFGxEzm8Q?t=6837As for how whores are a turnoff, I provided Dill as an example but as another anon said, there's the Ryuji clip as well which might be an even better example which I forgot about
https://youtu.be/giG-wOkqsek?t=4853TLDR: Yume culture is weird and every yume has her own preferences/kinks, they are stinky girls who are dreamers who self insert into fiction and are super into shoujo manga/anime and otome games
Here's a bonus clip of Bae being an ultra shoujo autist and going on a massive 20+ minute rant about some obscure manga she read last night
