Sinister Nights was born out of a frustration with the current state of conventions (Horror or otherwise). While there was nothing inherently wrong with these conventions, they were missing out on so much potential! It was with this thought that Sinister Nights set out to create not just another horror convention but a truly unique horror experience! We designed Sinister Nights from the ground up with the overarching theme of making it interactive for anyone who wants to join in on the fun and provide a wide variety events for everyone.

Lets start with the horror icons who horror fans will get a chance to take pics and get autographs from…

Sinister Nights promises to be more than the typical convention, and they will do that with some can’t miss events including…

Yes, you did read that right – we are putting on a 1980’s themed Monster Prom!!! Zombies, Werewolves, Vampires and more grab a can of hairspray and go WILD!!

We’ll be spinning your 80s musical favorites as well as flooding your senses with some amazing 80s imagery! To top it all off, we’ll be offering modern-style Polaroids so you can get that prom pic you always wanted / dreaded!
