Screen having constant glitch of lines/ghost-images across the screen

I was using my Macbook and it suddenly happened. The screen definitely didn't get accidentally opened too far or too hard, but it looks a bit like something isn't plugged all the way, if that makes sense. Like the lines that form the display are disorganized and moving/flashing around. I'll include a couple pics but it's a bit hard to see. Look at the lower half of the image where you can see the folder icon leaving this weird "gradient" or "trail":

It seems subtle on the image, but in real life when its moving and flashing around it is pretty distracting...
