Terrorists invaded the Nova festival in the early morning. The invasion led to a mass flight. Arbel had shown extraordinary resourcefulness when, with the help of her friends, they escaped the place. They tried to find shelter in the settlement of Alumim but were shot by terrorists and had to continue fleeing. Even though a bullet hit her, Arbel continued her flight. A friend's car picked her up, and she and her friends and other partygoers managed together to reach safety. Upon her return home, in the weeks that followed, she attended all the funerals for many of her friends.
