Random spinning to the right

Hello, I play on mouse and keyboard. I was playing earlier and everything was normal. Then, I died, got revived, and then when I came back to life, my character just randomly started spinning to the right as if I had a controller plugged in with a stuck analog stick (I do NOT have a controller plugged in). I'm not sure if anyone else has come across this issue but this is the first time that that ever happened since I've been playing since November. Like I have already stated, I play on mouse and keyboard and I run the game through Steam.
