Origins of Fear...

I wonder how we start fearing things. Where does the fear of unlikely/irrational things come from?

There have been a few nights the past couple of weeks where Calanit has awoken, run into our room, and cited a fear of "monsters" or "alligators."

We try to explain to her rationally that there's no cause for concern, but it doesn't always work.

Just strange how these things seem to appear out of nowhere...
