As you know hun, my Grandmother had premonitions throughout her entire life, and despite the fact that they weren't a regular occurrence (perhaps say 5 a year), every single time the event would occur exactly as she had foretold it. It never freaked her out, as her Grandmother before her had been capable of the exact same thing, so in some bizarre way it seemed perfectly normal.
As a child, and right into my teens I used to do the exact same thing, however in my case I found the dreams to be very unsettling, and in some cases frightening. Thankfully they are far and few between these days, but always scarily accurate.
My fear now is that my middle child is starting to do the exact same thing, and is struggling to cope with it.
I can understand why some might be reading this and rolling their eyes in disbelief; I think it is something that unless you experience yourself, it is very hard to wrap your mind around.
