I think I love you

I wrote this poem about a boy I've had a crush on for the last three years. Recently, I decided I was over him and the night I told all my friends that I was done with him was the night the nightmares of him stopped. Instead, they were once again good dreams and now I'm stuck on him again. Is it possible to love without really knowing someone? I believe in love at first sight and I believe that this is an example of that.
