Kate Hudson has confirmed that she can see dead people.
Westeros is not a place you would want to be in. It's not your typical medieval fantasy universe where plot armor is so thick and apparent (at least in the first four seasons) and people die there for the most minuscule of reasons. If it's not politics or poverty that will kill you, it's probably the White Walkers or their wight minions. Even the most likable characters are not safe from them.
