Loud noises was one mine when i was younger. I used to hate saws, lawn mowers, chainsaws, fireworks, and loud music. Course now I blast loud music, but back then, I'd run and hide somewhere and just cover my ears.
As for clowns, never loved them or hated them nor was I scared of them.
Storms I only feared when there were high winds involved. I had a fear of tornados back then. Though now I'd still get a bit nervous if I saw one.
I was also very afriad of masked people on halloween. Used to think they were real monsters. Espically the one that crawled down the stairs after me at this one house I trick and treated at.
That about pretty much somes up my childhood fears.
