Pretty much this, I hated water when I was little. When I was in the bath my parents would have to dump a jug of water on my head when I wasn't looking so they could wash my hair.  I also had to drop out of swimming lessons because I wouldn't go near the pool.
As for more recently, about a week and a half.  I had the flu and after fourish days realized I probably should shower.  Got up and went into the bathroom, turned on the water, got in the shower, after about ten seconds my vision went black and I started to pass out and smashed my shin against the edge of the tub. turned off the water, went back to my room, curled up in bed soaking wet and proceeded to not move for a few more days.
