A Florida hypnotherapist was arrested for having sex with a client whom he kissed abruptly during a session, police said.

Robert Andrew Nichols, 63, whose website bills him as a psychologist and paranormal phenomena investigator, was arrested Wednesday on a charge of being a psychotherapist engaging in sex with a client or former client, which is illegal in the Sunshine State, the Gainesville Sun reports.

A woman, who said she met Nichols during an adult-education course at Santa Fe College in Gainesville, told police in June 2018 that he started asking intimate questions about her sex life after starting therapy sessions with him, according to an affidavit.

Two months later, Nichols kissed the woman on the lips out of the blue during a session. Nichols then asked the woman to go to his home, where they had sex. He stopped charging her for his services at that point, the affidavit states.

Nichols and the woman continued to have sex and practice ritual magic — activities he claimed would benefit her mental health — but the relationship eventually fizzled out and the woman asked Nichols for a refund, according to court papers.

A detective in Gainesville interviewed Nichols in March, but he refused to say whether the relationship was sexual, according to police.

A message seeking comment from Nichols was not immediately returned.

An out-of-date website from 2015 identified him as Dr. Andrew Nichols and listed him as a member of the American Psychological Association, but a spokesman for the organization confirmed to The Post that he was not a current member.

Nichols worked as a part-time instructor for non-credit, recreational courses at Santa Fe College, including “Metaphysics and Parapsychology,” as well classes on ghost-hunting, witchcraft and voodoo, according to a statement obtained by The Post.

“At no time was he a professor who taught college courses,” the statement said. “Santa Fe College does not tolerate harassment, abuse or violation of professional ethics of any kind. As soon as the college learned of Nichols’ arrest, steps were taken to ensure he was not currently teaching nor known to be on our campus.”

Nichols has also appeared on several television and radio programs to speak on paranormal topics, including “Unsolved Mysteries” and CBS’ “48 Hours,” according to his website.
