One terrifying moment. The preliminary hearing of Sandra Bullock's alleged stalker Joshua Corbett is underway, and new details are emerging about the night that Corbett broke into Bullock's home.

Last June, the Gravity actress, 50, was in her Bel Air, Calif. house when she began to hear odd noises. In a tape of Bullock's 911 call from the evening, the star can be heard telling dispatchers that she thought the sound was the "wind blowing." 

The 911 call, which was played during Corbett's hearing on Thursday, paints a scary picture of just what happened that summer night.

"Someone's broken into my house," a fearful Bullock can be heard telling the police. "I'm hiding in the closet." 

When asked by a dispatcher if the intruder was still in the house, Bullock breathlessly added, "Yes, yes they are. I just saw them walk up into the attic... It was a man. I'm locked in my closet. I have a safe door in my bedroom. I've locked it and I'm locked in the closet right now."

According to the Associated Press, a police officer involved in the case also testified in the hearing, telling the judge that Corbett had on him a notebook dedicated to Bullock, full of photos of the actress and a letter he had written to her.

The officer added that when the LAPD arrived on the scene and arrested Corbett, he said, "I'm sorry. I love you Sandy." The AP reports that Bullock will likely stay away from the courtroom during the preliminary hearing of Corbett. He has pleaded not guilty to a variety of charges including burglary and stalking.
