I was reading your article on Trinity College ghosts and have a few stories of my own to share about the residence. There is even talk that there's a secret passage that leads up to Victoria College although no one I know has found it. The tunnels are warm, in some places dark, eerie, and it is easy for anyone to get lost down there. There is talk that somewhere in the tunnels is an old crumbling, brick and mortar wall. No one knows where it leads to.
Legend has it that a man was bricked up behind the walls.
His spirit sometimes wanders the tunnels. If he finds someone, he will drag them back behind the walls. With each person he takes, a piece of the wall crumbles. When he finds enough people, the whole wall will crumble and he is free to wander the tunnels at anytime. Apparently, he was a student in Trinity and he died during one of the wars.
