No. Fear of pen? Never heard of it before... But talking about fears being irrational, I guess that also goes hamd in hand in what people believe in. If you believe ghosts, demons, satan and so on exists which is irrational by itself, you will also fear them. Mostly triggered at places which you could imagine they would be present. Like abandoned hospitals and such stuff with cruel backround stories. Deep down in the darkness of basements. But meh, knowing that darkness cannot physically exist in this universe, what else should there be? You have to look at stuff from different perspectives.
So,... A pen...becomes ridiculous. It's just particular atoms on other atoms. One being what is ink, the other the paper.
