I don't know about you, but I used to be scared of being home alone. And now that Fnaf 4 is coming out, (and Fnaf is out) you might be scared more than ever. But here's the thing:

1) Freddy and his "friends" know what kills them. One of those things is water. So If you know that you are going to be home alone, take a shower or carry around a water bottle. This way you can ensure yourself that you won't have any visits from Freddy.

2) If you have pets, stay with them. Pets can sense unusual activity.

3) IF your allowed to, Invite friends over! From research, Freddy will only attack you if your alone.
