Understandings.... o.O

What does it mean when.....

You feel like embracing that someone really badly,

You want to stay by that someone's side every single second of your life,

You want to protect that someone with your own life,

You want to see that someone all day and night,

You want to talk to that someone everyday,

You keep thinking of that someone all the time,

You dream of that someone when your sleeping,

Your heart beats quickly when your near that someone,

You feel nervous when your talking to that someone,

You want to be special to that someone,

You want that someone to be yours.....

Seriously, what the heck does this mean??

Because i have all these strange feelings that i don't understand right now.... :'(
