I think I may possibly be insane...visions of the future?

it sounds like you are somewhat obsessed with these "premonitions" as you call them. Fact is most of what we call premonitions are simply self fulfilling.. you think about them happening and you put yourself in situations where what you have been thinking happens, You might benefit from some counseling over your obsession with this, but I don't think you are insane or abnormal.
