Sounds kinda like OCD

Ok but I have a picture of me crying on A mall Santa’s lap as a kid so you are not alone

I don’t know the name but it would be because of the uncanny valley where something looks realistic but off like a robot with a fake human face, taxidermy would probably give off this same vibe esp...

It’s considered a sign of being a psychopath or sociopath if you don’t fear rejection/don’t care about rejection so yes a fear of rejection is 100% normal
