I know what you are talking about, since i was 14 i had true dreams. I had my dead uncles taking to me and stuff.
I usually tell my friends about my dreams. I can usally tell that if some thing major abut to happen(only in my life and stuff)
But as you said some time we get so lost in every day life, we become sad and stuff … and some dreams bring so much peace to heart.
Its like some one is showing you bigger pictuer.
