Why doesn't my phone screen respond?

My phone doesn't work. The case is that I used facebook and then there was a facebook noti on my phone and suddenly I can't drag or swipe my phone screen. Moreover, volume and screen on/off buttons don't work ,too! So, my phone screen is still open. What can I do?
