>Hello my name is Niklas and i wont to know what can i do if i am dead and my ghost falls down netherstorm and i cant do anything against it?

there were better places to ask your question, such as the general forum ( http://thottbot.com/F/General ) but ok ..

in the bottom bar, there should be a red '?' icon
click it. then follow the steps untill you find the stuck section and click the unstuck button -- or create a ticket through the same section and wait for a GM to talk to you
