blood in video games absolutely terrified me, but in movies and tv shows it was whatever
the martians from Mars Attacks scared the living stuff out of me and gave me nightmares
i have always been, and still am, scared stuffless by plain, featureless faces floating in darkness
i used to have a really bad phobia of seeing a clone of myself but it's a little less severe now
also
heavy graphical glitches when i was younger.
those are not all of my phobias, but i think most of my other phobias would be classified as pretty sensible/normal
