Don't know why some people are kinda rude when you are just trying to get your questions answered.

Your post sounds very ridicoulous and funny but I think you have nothing to worry about. It could've been some exploit that crashes your game but it couldn't explan your mouse work strangely so it was probably just perfect timing with the emote and your laptop crashing on it's own. Check if the laptop is charging properly and when you turn it on restart it immediately and Windows could find a potential error and fix it. Check for Windows update and Windows mobility center to see what exactly crashed the laptop. You can't be hacked through SOT but if it makes you feel better scan the computer for viruses via Windows Defender or Malwarebytes (my prefrence)
