@HikiNeet: first of all, thank you very much! I agree with you, that sometimes words make the atmosphere creepier than jumpscares... The only problem is, whether I can manage to do it, or not... ToT
Anyway, about the characters bios being not that "informative", it's always been one of my problems with writing... I mean, I use this method because I'm the type of person, who when writes, unwittingly spoilers too much. So, I thought, that using this "detached" way of writing could make the reader more interessed about the character... But I'm not sure, if that was the right decision :(
Anyway, thanks a lot for your examples! I will try to improve my way to write characters bios :)
