Dead girl in Fractal

Our group was dancing late till about 6:30 am at Fractal Forest on the right stage side when a security guard came to check on a girl sitting against a tree next to us. She bent down put her hand on her shoulder to check if she was okay and quickly panicked when she realized her state, shaked her and the girl fell limp. I’ve never seen anyone so ghost white which happens usually 20+ minutes after death. There was a lot of panic and everything felt dark as security consulted what to do next. We all stood in shock at the scene and quickly decided it was time to leave. If anyone knows anything about what happened to her, I’m pretty messed up about it today. I hope she’s not dead but the feeling and vibe was that she had already died unnoticed for some time.
