Is a clicking or crunching noise normal for iphone?

I slept on it last night and started making a clicking and crunching noise when pressed and slightly pressed

Like when you click the home button? The home button is fine if it does that but if its not the home button you might want to go check it out. Usually it doesn't really do anything if you sleep on it, I've slept on mine before. But if it sounds not normal and if it sounds like its breaking, go get it checked on.
