But don't worry, you didn't sleep through the apocalypse.
It was World Zombie Day on Saturday (10 October) and hundreds of un-dead freaks covered themselves in white face paint and fake blood to mark the occasion.
Zombie babies, clowns and brides were just a few of the gruesome attendees – all to raise money for homeless charity St Mungo's Broadway.
The event's website says: "World Zombie Day is an international annual event that grew from Pittsburgh's first Zombie Walk at Monroeville Mall in 2006 – the site where George Romero filmed Dawn of the Dead – to help all fans of Zombie culture come together in an international effort to relieve hunger and homelessness."
The gory affair came just in time for the start of the season six of The Walking Dead this week.
Fifty other cities across the globe took part, donned their white contact lenses, and perfected their zombie shuffle to celebrate.
