"But tonight, we are out to claim the streets, to fill the streets with the audacity of our dreams and desires," she adds.
Shambhawi Vikram, a 23-year-old arts student, who lives in a private hostel — which are called PGs or "Paying Guest" hostels — says the restrictions are "humiliating" but being locked up can also be dangerous and life-threatening.
"Two years ago, there was an earthquake in Delhi. As our building shook, all of us who lived on the lower floors rushed out, but 20 students who lived on the fourth and fifth floors were stuck, because they were locked up. It was frightening, they all ran out into the balcony and looked at us. We could only look at them. We all felt so helpless."
Rafiul Rahman, a 23-year-old postgraduate student who is among the protesters, says the march to claim the streets is "unprecedented" and "historic".
"Something like this has never happened before in the university. It's crazy to lock up women after 7pm. You have to question and challenge irrational norms."
Mr Rahman says whenever he steps out at night, there are a lot of men sitting and smoking and drinking chai, "but you don't see a single woman — and that must change".
Campaigners say that the idea that locking up women will keep them safe is very flawed logic.
"You can't keep women safe by keeping them away, it does not make any sense. Streets will be safer only when we have more women on the streets," Mr Rahman says.
With their night walk, Ms Kalita says, "we are trying to create a new imagination, about what public spaces could be like".
Protests by students in the past have forced the authorities to relax timings somewhat, but the Pinjra Tod campaigners say that's not enough.
The campaigners are using social media to mobilise students — and others — across Delhi and beyond to broaden their movement for freedom.
Ms Vikram says in India, women across ages and class live in cages and they have to fight to escape these prisons throughout their lives.
"Some 40-50 years ago, women had to break the cage to get in to university, today we are trying to break the cage to get to the library after 7pm.
"Even Cinderella could stay out until midnight. Why can't we," she asks?
