JACKSON, Tennessee (CNN) -- Candra Pennington huddled in her dorm room at Union University with about 15 other young women Tuesday night as bad storms swept through western Tennessee.
Students rush to the scene Tuesday to help people trapped at Union University, I-Reporter Mark Inman said.
At first, Pennington said, the students at the liberal arts Southern Baptist school in Jackson were "laughing and kind of joking," thinking they didn't have much to fear.
But suddenly, the heart of the storm was upon them, and they had to scramble to a nearby bathroom for shelter.
She said they barely escaped.
"As we were closing that bathroom door, the debris and the windows were shattering in with us and the ceiling was beginning to fall in on us," Pennington recalled.
"When we came out, we were just shocked at what we saw -- to see that all of our belongings were gone, that if we hadn't made it to that bathroom, we wouldn't have been OK." Watch as the student describes a terrifying night »
"Everybody was trying to jump right in and get people out from under the debris," Inman said. "A lot of people were shaken from being under the debris." Watch a student describe being pinned under concrete »
Amazingly, no one was killed on the campus of about 3,000 students. Two dorms were "completely ripped to shreds," CNN correspondent Ed Lavandera reported from the scene. Watch a survivor describe how the building he was in imploded »
About 1,200 students were believed to be in campus dorms at the time of the storm. In parking lots Wednesday morning, cars were flipped over like little toys, their windshields busted out.
Sophomore Andrew Norman said he and others took shelter on the ground floor of his dorm and also fled to a bathroom. He said he got chills as he watched the swirling winds. "The windows exploded and all this dirt came flying in. I've never been through anything like it, for sure," Norman said.
He added, "We're all fortunate. We all made it out OK."
The school has shut down for at least the next two weeks, said university President David Dockery. He said every building on campus sustained some type of damage and estimated damages of $40 million to $50 million. Nine students were hospitalized, but officials said none was believed to have life-threatening injuries.
"Our students were very courageous last night," Dockery said. "They handled an incredibly challenging situation with grace, and they pulled together and helped each other."
At least 52 people have been killed in the storms that wreaked havoc across Arkansas, Tennessee, Kentucky, Mississippi and Alabama, emergency officials said. Watch one witness say he's "glad to be alive" »

Ben Powell to CNN affiliate WPTY-TV in Memphis after a storm hit a mall in the Tennessee city
"I know it sounds cliché, but for a minute there I thought it was the end. It was pretty creepy. I've been in some tornadoes before, but I was just trying to stay calm, you know, and stay down."
Unidentified man at the mall told WPTY
"People started screaming and hollering and everybody just broke out running. ... I was thinking about my mom, and I was calling on Jesus."
