People think I'm crazy when I say this but personally I feel phobias stem from repressed bad memories of a past life.
I wouldn't think you're crazy. My other phobia is ships. I hate ships and you would NEVER get me to be on one. I have this distinct memory of being a child on a sinking ship with another ship there to rescue us... there's some sort of bridge and I am crssing the bridge... my shoes fall off in the water... no idea where it comes from but I won't go on cruises or anything Not even riverboat casinos.
