Why does my phone crash then show a pixel-ish screen with diffrent colors in them?

[Android Central Question]

So, sometimes when im just in bed, i hear a buzz off of my phone. I go turn it on to see if it was a notification. Then it flashes this pixilated rainbow screen at my face and then it puts the screen there again bt it will stay for 2 minutes or so. Its colors are white, blue, yellow and red i think. And each time it happens, it or reboots or it is stuck in this endless loop of recrashing and heating up my phone.

The only thing i have noticed while in this rainbow state, is that it is taking screenshots when i want it to. It also reacts to the home button. It does not react to the touch screen or sleep button.

I have a samsung galaxy S5.
