Yes, I do fear that something may be trying to keep you from APing. When there is a restless spirit or harmful spell near, the first things who tend to notice are the animals and nature. Look to them not in annoyance but in gratitude for alearting you when evil and harm is near.
Also, before traveling, try using an anti curse spell or a spell to ward off evil. Then if the animals don't get loud, you know your safe.
