These are mostly things I listen to on Youtube and I don't know how "weird" these are, but:
History concerning witches. Since it's usually rooted in ableism, misogyny, racism, xenophobia, and the status quo (church/men/etc) struggling to remain in power.
Interesting or tragic history. This can range from true crime to Victorian era medical to interesting ancient history. Ranges from AskAMortician to Puppet Theater on YouTube.
True crime. I know I mentioned this above, but there's so many stories in older true crime that makes me wonder if the victims were LGBTQ+. Sometimes, it's never even considered, and it's sad, since that's possibly a part of the victims that was possibly completely lost.
Animatics. Love me some animation or animatics put to music. I'm so envious that the younger generation can use YT for this. I've been tempted, but I usually turn that energy toward my webcomic.
Myths & Urban Legends & Creepy pastas. Kind of goes to the above, too, except to scary stories. Unless it's an analysis of mythology or urban legends, then it's informative and entertaining.
Media analysis or reactions. Movies and cartoons, mostly. I'll even watch these things about shows I hate or things I haven't seen yet. There's something really great about watching people's interactions with a form of media. It's similar to how I hope people will interact with my content one day.
Doll customization. Particularly Monster High dolls. I actually started customizing one, but I lose motivation/time/energy by doing other things. I'm hoping to make a Thea and Noth doll, one day.
Dramatic make-up. Like above. I'm interested in it, but I don't have the time/energy/motivation to try it consistently. It also gives me ideas on drawing make-up more effectively, I think.
