I remember my friend and I were waiting for people to pass us so we could find her parents easier, we were stood up from out seats. The last song ("Dangerous Woman") had played and all the lights had turned on, roughly 15 seconds later there was a loud bang. At first everyone stopped, the fear rushed through people's heads as they started to run towards the closest exit.
Meanwhile I was staring at my friend panicking, I had no idea but the only words that could come out of my mouth were 'We're going to die'. It scared to get slight foggy in the room so we panicked even more. We quickly rushed to an exit trying our hardest to not get hurt because we both thought it was a terrorist attack. You don't realise it will happen to you until you're actually in the position. It's extremely scary and very damaging to your mental health.
After Ariana said her goodbyes to all her fans, the explosions went off. Everybody ran out of the arena either crying, some left their children there, some ran out with blood on their clothes, everybody was evacuated, it was horrible.
