This is definitely a problem only Kane understands, as WWE storylines never really cleared it up. Basically, Kane was haunted by 'voices' in spring 2006 that indicated something sinister about May 19th. Kane was freaked out and it seemed like the date held some sinister event from his past. May 19th was actually the date of release for See No Evil, the WWE Studio movie that was starring Kane. As a promotional ploy it probably did help to create some interest for the release, but ultimately the May 19th wrestling storyline went nowhere. It is just one of those wrestling narratives that WWE wants you to forget. As for Kane, only he'll really know why that date is so traumatic!
