Was there something you were afraid of as a child that just seems silly to you now?
I was freakin' scared of EVERYTHING. Basements - I grew up in a big Victorian in Baltimore, with a dank, concrete cellar that contained many, many relics of long ago past smothered in cobwebs - and in order to get my $5 a week allowance, I had laundry duty! The washer and dryer were in a corner of the basement filled with shelves of old pickling jars (many which still had food from the '50s and '60s in them - my mom grew up in this house). So whenever I wnet down, I crossed myself and said many prayers that basement spooks wouldn't consume me (I was also afraid of ghosts and demons, which I believed roamed the house).
I was also afraid of leftovers, dogs, ticks, roaches, mold, looking up in the sky from a high place, ie. the jungle gym at school (though not looking down, strangely), creatures hiding at the bottoms of muddy lakes, rock music other than the Beach Boys (everything else was Satanic), sharks eating me at Ocean City, the monster under the bed (of course), finding literal skeletons in closets (the home I grew up in had many doors and passages, and I believed there were decomposing bodies in them), teenaged girls (I would watch them, so cool, walking in gaggles from the nearby private school with ice cream sodas from Baskin Robbins, and imagine that they were casting disdain on me, so I always hid from them), watching a toilet flush (I believed that when it was finished, a spirit would devour me - DON'T LAUGH, haha), the way cat eyes glowed in the dark, the movie Amadeus, snakes, drugs and any sort of pill, and, of course, Satan.
Reading this, you're probably thinking I was a freak kid who lived in a closet, though actually, I was a happy (though serious) kid who had a pretty normal and fun childhood with lots of friends and family always around (Baltimore is where my mom's side of the family is from). I still have some weird phobias, but I think moving out of that house when I was 10 dispelled a lot of my more crippling childhood fears.
