Spooky is the most neglected of the five basic human emotions: spooky, joy, sorrow, grouchy, and wet. Get horror glands pumping with today’s Groupon: for $25, you get a VIP Extreme Night Pass to Callson Manor Haunted House, located at the Placer County Fairgrounds in Roseville (a $60 value). Callson Manor is open on select dates in October, from 7:30 p.m. to 10 p.m.

Owned and operated by a professional animatronics designer, Callson Manor Haunted House engenders human terror with realistic sets and engrossing special effects. The VIP Extreme Night Pass offers scare seekers unlimited access to the Manor’s eight professionally designed attractions without waiting in long lines or cramped torture chambers. The Panic attraction immerses the senses in simulacra of classic phobias, and Miner’s Revenge forces investigators to navigate a mine haunted by a disruptive spirit with a penchant for explosions. VIP-pass holders can also watch others yelp in terror from the safety of an exclusive lounge, allowing them terrorize other visitors with the push of a button. After the frightfest ends, VIP visitors can explore the Manor during a special guided tour starting at 10 p.m. that reveals the house's special-effects secrets and embarrassing fear of long-legged spiders.
