Open the facebook messenger app > Menu > settings > Notifications you can unchecked this. 

Could you elaborate regarding "turn on the screen a lot of times"? Do you mean that when you get a notification the screen turn on? If it does do you have a notification app or a different home launcher or a different lock screen app? 

Don't forget to give Kudos
