Double Death

I saw two people die, one of them was a teen guy that was hanging on a bridge on a river near my house and people from the greenhouse asked him if he was okay and he nodded, and when he fell down, he used the moss as a slide but then he died. And another one was an Indian mother that was doing aerobic dancing on the train station rails in the city centre and then the train hit her, in that train, there was also a slightly hazardous gas, but i entered anyways, but I felt dizzy.
