Wow, Omnivorous. My condolences. I can't even begin to imagine, so I simply won't.
I did have a few fears as a child, and one still itches. The first came from watching the movie IT, based on Stephen King's novel. I just remember feeling completely paralyzed and helpless while watching that movie; just like some children were when they looked at the light of his eyes, and followed him into a sewer or around a dark corner.
The second fear is the same as Brenna's, and it still "itches", which basically means it's there but I can manage it; and that's swimming in deep water. My head is above water, my eyes scan, but underwater are nebulous shapes with no sound. My body feels vulnerable; we are slow in water, cannot breath in it, and on and on.
Again, it's the vulnerability that is attached to me while in the deep.
Good topic. I'll get off the sofa now. How much do I owe you?
