Does anyone believe in love at first sight.?

Like I'm so serious. Listen to the song "I knew I loved you" by "savage garden" it is very true for me. And maybe some of you guys can relate. Ijust wanna know if I'm alone on this one. Because ibelieve that iloved him before iknew him. Iknow it's crazy., and maybe a little awkward . But ibelieve in love at first sight and ijust know that I'm gonna marry him someday. Does anyone else feel this way or am I alone.???
