Sadie is very afraid of loud noises, particularly thunderstorms or fireworks*. (If anyone has suggestions to help us with this, we'd appreciate it.) When a storm comes, she will hide in a far-back corner of the basement. Eventually, she'll emerge and sit by the back door.
Here she is in her "safe spot."
*When she is scared, we generally let her hide or do whatever she feels is safest. We just wish she didn't have to feel so scared. :-(
