Strange Distortion in Camera Rendering in Unity 5.5.2f 3D Game

As you can see in the screenshot, lines are being rendered across the scene. I have no clue what has caused this. Can someone please help me? I am new to Unity3D, so I have very little experience with this type of thing.
Thanks in advance!
Edit:
I tried reimporting all assets, the problem is not fixed and now the lighting seems messed up.

Edit #2:
It turns out that my scene just got corrupted somehow, I made a new scene and I am no longer having this problem.
