Narrative:

1 hour after takeoff; the cockpit called #1 flight attendant and #3 flight attendant answered. The captain said that there was an indication of a slide being deployed. #3 flight attendant went to the window exits to check the windows but everything apparently looked ok. About 1 hour before landing in ZZZ; #2 flight attendant was in the aft galley and called to let me know that a lady seated in 16A was upset because she was going to miss connecting flight in ZZZ and that we did not have any pillows on board. I went to talk to the lady at 16A. I stood in the aisle for about 10 mins and explained to her that she was going to be able to make her connecting flight because she had 1 hour on the ground in dfw once we landed and I also explained to her we only carried pillows and blankets on international flts and that ZZZ1 was not really an international flight because it was inside the united states and that was the reason why we did not have blankets and pillows. While I was in row 16 in the aisle; I saw a quick shadow in a window on the left side of the plane and followed by a strong noise (it sounded like a bomb) and the plane shook for a few seconds. #4 flight attendant was watching first class and ran towards me. I could barely fell my legs and I had to remain calm since I was right in the middle of the plane and all passenger were looking at me. (They looked so scared; it scared me too! Some passenger were crying and some moved right the way from the left window exit area to the right side of the plane). I started looking through the window trying to see if there was fire in the left engine or something like that when I remembered to check down then the windows right after the wings and I could see the part of the slide flying. I found out that the cockpit had declared an emergency landing. Once we landed and the captain made an announcement that some emergency equipment and the fire department were waiting for us to check the plane before proceeding to the arrival gate. After a couple of mins; we were towed in to the gate. And once we opened the door; fire men came to the cockpit to talk to the captain. The ground personnel that met the flight had no idea what had happened to our flight. It was very scary! (And on top of things; I was chosen randomly to go for a drug test after this 4 day trip!) we did not have a debrief upon arrival in ZZZ.
