Love?

I was thinking today. How do we define love? I could google the whole world on the internet, but no where does can I find what love is.

I think it's like faith, religion, a belief that no one can teach you, but not a practice, because a practice is something you do out of routine-ness, not necessarily desire. So it is what people say, it's something you define for yourself. And today I'm having such a hard time defining it for myself. Not in words because maybe it's a language of no physical or emotional words. But...I can't even define it in thoughts, because I can't understand my thoughts.

My tummy hurts :-(

What we all ask for and want are secret mini-manifestations of our dreams and desires. Sort of like Freudian psychology :D but not so extreme!! So back to my question, why are people afraid to dream? Why are people afraid to desire or want? Why are people afraid to go get what they want? I guess we all kind of know why :-/
