'They were much taller than me and started hugging me even though I did not want them to. Then they started grabbing my breasts very roughly.
'I felt so small and vulnerable. It was as though I sank down in to the ground. Like there was nothing I could do and I was in their possession. I had felt safe, proud and strong up until that moment, but now it was all gone.
'I kept asking them to stop, but they only left after my colleagues saw that something was wrong and came up to me.'
Ms Florman added: 'The ironic thing was that they were wearing the police bracelet with the text 'don´t grope', everything was really surreal now that I remember it.'
As well as reports of rape at the festival - headlined by Mumford and Sons - there was one report of attempted rape and 15 cases of sexual assault.
Two of the victims, most of whom were girls under the age of 18, said a man masturbated in front of them, while others said they had been filmed while using the toilets.
Police in Sweden have faced criticism for failing to do enough to protect the 52,000 festival goers.
'Maybe they want to take it seriously and they are on their way towards understanding after quite some time,' said Ms Florman, who runs a non-profit organisation called the Night Shift that aims to create a safe environment for women at festivals.
'But very little is actually being done. When I come up with concrete suggestions for festivals, they don't take me seriously and they think that I don't know what I'm talking about. They don't listen to my advice.'
Police spokesman Thomas Agnevik, who was also at the festival near to Norrköping, said he 'understands the criticism'.
'If a crime is being committed obviously not enough has been done,' he said. 'Nobody should have to go to a concert and leave as a rape victim.'
But he added said that police are almost powerless to protect festival-goers, as most of the attacks happen among crowds of people and often after dark, making it is 'very difficult' for them to spot those responsible.
'Two of the rapes happened in front of the stage in the crowd, another was in a tent and another in the public bathroom,' he added.
