At the beginning they give you some options to choose from, I choosed not to talk to the ghost in case it was evil, and collected some bones I thought were needed for something later on, but now I am carrying 3 bones for nothing and after research I found that I needed to talk to the ghost in order to trigger a mision, now I can't get rid of the bones because it says it is for a mission but the mission doesn't exist and I can't talk to the ghost because I choosed the option not to at the beginning and the game doesn't allow you to talk to the ghost anymore.
Does anyone know what to do?
You missed the quest, it even happens in paper role-playing games. Apart from reloading an older save to recover the quest by changing your answer, there is no (and this is normal) other solution.
Quoi que tu dises, quoi que tu fasses... I speak bad English... so what?
