Imperfect Precognition

I have precognitive abilities (it means I can see the future). I dream of certain events that come true after a day or two, maximum a week. My parents have it too, and my brother just might have it. But I think it runs in the family, since my great uncle can channel bioenergy, and, among other things, see the future. The problem is that neither my parents nor I see important events, we only see it in dreams, and we don't know if it was a dream or a vision of the future. The very first one I had was in January 2012, and it was about a video game I bought ("Star wars: Empire at war" if anyone wants to know). Anyway, the night after I bought it, I saw a scene from the game in a dream. Tomorrow I was playing the game, and saw the scene that I dreamed. I was stunned, and I had no reasonable explanation for it, as I never played the game before, and I didn't watch any videos of it on the internet. A few days later, we went to see our relatives from Australia, and I dreamt of my cousin hide behind a curtain. Tomorrow we were talking, and my cousin's younger brother embarrassed her, and because of that she hid behind a curtain. It couldn't have been a simple "deja vu", as we haven't met until that day due to my uncle (their father) leaving my homeland 3 years before my birth. My great uncle however, can control the ability, and does see important events. I'm not sure how far does his ability extend as I didn't get a chance to ask. But some friends of his were trying to have a baby, and they just couldn't. The wife was 46, so very unlikely to get pregnant, and one day my great uncle's wife told him that they need advice from him, and he answered: "Just call them and tell them they'll have a son soon". I really want to improve my precognition, so does anyone have any advice?

P.S. I can't go to my greatuncle because he lives far away from me.

Any sort of help is useful
