Donya sits sobbing inside her car on a busy Tehran road as deafening horns ring out around her. She fears she's about to be killed.
She is among dozens of others who have set up a blockade with their cars as people take to the streets in Iran to demonstrate against the government.
The group is risking their lives in a desperate attempt to stop security forces from reaching protesters at a nearby university.
"They're killing our students," she sobs into a voice message to the ABC.
"I'm driving there and the highway is full of cars and everybody is horning, trying to stop the guard cars.
"I don't know … we just try to help but they keep killing."
Speaking with foreign media is incredibly dangerous for Donya, so the ABC has changed her name for her protection.
Other Iranians who have spoken out against the regime have been arrested, detained, or killed by government-backed forces.
In the past month, thousands of ordinary citizens – led by mostly young females — have massed on streets across Iran, chanting anti-government slogans in the most significant unrest in the nation in years.
The protests began on September 16 when 22-year-old Mahsa Amini died after being arrested by morality police for not meeting Iran's strict religious dress code.
Headscarves came off in defiance of the Islamic Republic's hijab mandate as some women and girls filmed themselves slashing through their hair.
The protests have persisted for weeks, prompting the government to ramp-up its efforts to suppress the public outcry with its security forces.
But women like Donya say they won't stop protesting until the country changes or there is a lasting revolution.
'The price of freedom is our blood'
The "feminist revolution", as Donya calls it, has given her confidence to walk outside to local cafes without her head covered.
But she's aware she's dicing with death every time she goes out.
"You're scared for your own life, and when you go out, you're not sure if you'll go back home alive," Donya said.
"The price of freedom is our blood."
The Gasht-e-Ershad, known as the morality police, are tasked with enforcing the country's strict dress code, which requires all women above the age of puberty to wear a head covering and loose clothing in public.
Each time she goes out, Donya takes extreme measures to avoid being identified by guards.
"It's like a war zone. You don't know when a protest will happen and, even if you are not participating in that, you have to be ready for everything," she said.
"I carry my backpack with extra T-shirts because they [the guards] use paintballs when there is a protest, so they can identify you and later come and arrest you.
"So I always have a few extra T-shirts with myself to change, and alcohol to clean the paint."
She also takes other precautions and doesn't leave home with her phone.
"If they arrest you, when they search your phone, they search all your accounts and if they see you've posted anything against them, then it will be worse for you," she said.
"If you use your phone at a protest, they might shoot you."
Life inside Iran's repressive regime
Riot police, government security forces, and armed soldiers have targeted protesters and bystanders during the deadly state crackdown on dissent.
The Norway-based Iran Human Rights organisation said the civilian death toll during the unrest has reached at least 201 people, including 23 minors.
Some of Donya's friends have been detained and others have witnessed killings.
"A few of them, they are so traumatised, one of them can't speak for three days," she said.
"I have a few friends who can't stop crying, because the guards killed somebody in front of them."
The ABC has been speaking with Donya over several weeks, but communication has not been easy.
It is almost impossible for journalists to enter Iran and a government-imposed information black-out means the internet is frequently cut off.
Several social media sites have been blocked in the country.
Iranians have also told the ABC they are wary of their online communication being traced by the government, and their details being disclosed to the country's regime.
Despite the risks, some Iranians have managed to find ways to contact foreign journalists or touch base with family overseas.
Donya said she wants to share her experience as a woman, to help those outside the country understand the helplessness of her situation.
The defiant chants echoing across Tehran
One evening, Donya went out into the west part of Tehran, where police were shooting tear gas "but not much".
She witnessed a man being attacked by guards in front of her until he was taken down with a taser – otherwise known as a shocker.
"They use shockers mostly, they almost killed someone near me … not sure if the guy survive … four of them attacked him," she wrote in one message.
"I tried to go help but a few guys stopped me.
"Can't stop my tear till [sic] now."
At 9pm each night, people in her neighbourhood turn off the lights in their homes and start chanting together "death to dictator" or "women, life, freedom".
"They stand behind the open windows so you can hear them outside the house," Donya said.
"But they turn out the lights, so nobody knows which house it's coming from."
The chants echo around the block, a symbol of feminist solidarity.
"It just gives you the feeling like you're not alone, and [the regime] are going to pay the price for what they've done to this country."
Like Ms Amini, and many other women across Iran, Donya has previously been arrested by morality police for having "inappropriate" clothing.
The ABC has chosen not to reveal the exact details of the case, to protect Donya's identity.
"They put me in a van, it was so scary, you can easily get killed," she said.
"Where they took me, everybody was screaming, everybody was crying and shouting. Still sometimes I have a nightmare about it.
"They give you some forms [to sign] saying 'I'm sorry I did this, I won't do it again, my apologies, I promise that I will wear more decent clothes.'
"And the funny thing they ask you is: 'what is your motive?'
"And there are a few multiple-choice answers, and one of the answers is, 'I got fooled by news agencies outside of Iran.'"
The Committee to Protect Journalists said 35 journalists have been arrested in Iran amid the protests.
Iran is 'alive with hopes and dreams'
Iran's Supreme Leader Ayatollah Ali Khamenei has condemned what he called "rioting" and accused the United States and Israel of planning the protests.
The Ayatollah warned that those who fomented unrest to "sabotage" the country deserved "harsh prosecution and punishment".
Donya has broken down in tears during multiple conversations with the ABC, but hopes her country is going through a revolution.
"People here are not obeying anymore, people are not 'good citizens' in terms of the dictatorship," she said.
"We are alive with hopes and dreams.
"If we win, it will be a victory for all women."
