Things I no longer understand but did when I was younger

When I was young I believed in Karmic causality. I remember thinking of the world in opposites, and when one happened the other would inevitably occur as well. I am still convinced that it is true. There were too many times in my childhood when I observed this phenomenon. Like when I saw the color red, I knew invariably that I would be drawn to the color green. When I saw the earth, I knew that I would see the sky. When a person died, someone lived. Etc.

But now, I can't understand it, nor can I see intuitively grasp that concept. It seems that the world is just too big for that thinking now.

Also, I still believe in premonitions. I've had it many times when I knew something would happen, and it did. It usually happens with people. I see someone that I think I know, on closer inspection it turns out it isn't him or her. BUT, within 5-10 minutes, the person that I thought it shows up. Isn't that weird? And it's not with people that I know, just people that I see around campus alot.
