My lock screen keeps going on by itself.

[Android Central Question]

When I got my phone it was awesome, but now after some updates my phone plays disco and it is very annoying. My phone is locked and left alone, then the lock screen goes on by it self. It will stay on till it goes to sleep then it will go on again. It looks like my phone is playing disco? What is wrong and how can I fix it?
