Aside from comics, I also work on novels, visual novels, video game dialog / script, voice acting kind of, nothing official, more like reading books out loud in 'voices' is a common one, specifically the voices that have been appointed to the pets in the house, because... that's a thing, the animals have voices, everyone in my house talks for the animals in our house with the animals appointed voice.
I'm not sure what you call it, my little sister calls it being a nerd. I guess it's kind of like RPing but more random and with hundreds of characters acted out by 2 people.
Basically my little sis has a lot of OC's so she'll try to get them to interact with the characters in my comics and books by just going up to me saying stuff like "Atsushi and his band are is going camping, Andrew should go to since he's working on being a singer, it would be good experience for him. Actually we should just make his whole class go so that all their parents can have a break with them going off to camp." So then I get to be the voices of all my characters on this weird camping trip my sister made up with volcanoes, trees that grow instantly and whatever else kinda things she can think up.
It's really pointless and silly and makes no sense, but I think it counts as a form of storytelling.
