Clicking noise from my iphone 6?

I've got a new iphone 6 that i got today, and i've realised that there's a weird clicking noise when i'm barely pushing the home button, it almost seems like its loose or something? Also i don't know if its just me or its the same to all, but i think my home button is in deep, or its just the silver ring around it thats making it feel deep, but i don't know please help! I'm freaking out

It's a ghost. Definitely a ghost
