Oklahoma native Dolly Litke, 43, believes she grew up in a haunted house. She co-founded Shadowz Paranormal Investigations in Biloxi last March with her son, Jared.

"I wanted to help people because I know what it feels like to live somewhere that you are terrified," she says.

Litke is one class away from becoming a certified paranormal investigator, having completed three online courses through Flamel College, a Web site offering classes in alchemy, parapsychology and certificates for Wiccan practitioners, tarot consultants and wizard apprenticeships.

Shadowz investigated a Jackson home last weekend in which the 27-year-old homeowner reported hearing an invisible baby crying and woman screaming. Litke's group took electromagnetic field detectors, infrared monitors and video and night vision cameras to the site where they recorded around 40 hours of evidence they are still examining.

NOTE:Correction to this article.

Dollu is already certified in Paranormal Investigations, Advanced Paranormal Investigations, EMF & White Noise Technician. She is one class away from my degree in Parapsychology.

UPDATE: Dolly Litke completed all the classes and has a degree in Parapsychology.
