How likes who

How to know or to be that person, how i should do the first step, how to know if im here or is just a dream in my sunday nap?. Who is this person? if i want her anyways, maybe for one night or a day, maybe for 30 minutes (i hope for more) but,how to know the end of this, i know is not for ever, is just a momment, maybe is the infinit.
When you wish something, you wish somebody? i hope so too, take a chance, like the morning. I am that "who" and i dont have any idea of that "how", how i can show her, how i speak, how is touch, how i should put in order my words or that song when i never been in this situation before, i want it today, i want it tonight but i dont know how to do the firs step, i should go to sleep without a "who".
