I would not share with anyone what I'd see.
Looking at it as realistically as possible (if the situation really existed) the glimses of what you'd see (imo) would be vague images of a situation, leaving you with an uncertainty that what you've seen will definately occur or might occur.
Given that a person's actions can change their future, telling anyone what you've seen will not help matters since the future is changable with a blink of an eye.
Playing around with something that hasn't occured yet is not a good idea.
