nametagophobia
nametagophobia refers to the hallucinations of small gray rectangles, often referenced to the name tags from the 2009 video game "Minecraft". Some hardcore sweaty players of the game often see these Name tags in the real world. This phobia can be generated by playing Minecraft with other people for long periods of time.
