Visitors who allow themselves to be lured into a haunted house in Santa Rosa may be met by La Llorona, evil witches and black cats— 13 black cats, to be exact.

Though the number 13 is considered an unlucky number to some, the owners of Blind Scream intend to celebrate their 13th year offering a haunted house experience to Sonoma County. This year’s theme: The House of Superstitions.

“We don’t claim to be the scariest, but we claim to be the halloween-iest,” said Drew Dominguez, co-owner of The Blind Scream. He and his long-time partner, Judy Groverman Walker, will open the haunted house on Oct. 7. It will run for 13 nights to commemorate this special year.
