Uma Thurman's parents weren't exactly psyched to get some "creepy" emails from a fan who had a big crush on their daughter.

Taking the stand today in the trial of Jack Jordan, a former mental patient accused of stalking the Oscar-nominated actress, Robert Thurman said "air-raid sirens" went off in his head after receiving the chilling missives.

"I was trying to remember the number of the FBI," the elder Thurman told jurors in a packed NYC courtroom, per the New York Daily News.

The Columbia University professor testified that the Thurmans were sent 19 emails that detailed the 37-year-old Jordan's increasing obsession with the Dangerous Liaisons star and raised serious concerns about his daughter and her two children's safety.

 

" 'Today, the center of my forehead is ticking now and then. I feel in love with your daughter Uma,' " he read aloud from one of the notes.

Earlier, mother Birgitte Thurman testified that she first encountered Jordan, a Maryland native, in 2005, when he phoned the family residence and informed her that he and the blond beauty "had a predestination to be together."

Jordan was arrested last October outside Uma Thurman's Greenwich Village pad and booked on charges of misdemeanor stalking and harassment. He faces a year in jail if convicted.

Thurman, who turned 38 today, was not in court, but could testify as early as tomorrow.
