Is it normal to be afraid of what's under you in water?
I'm scared of swimming. I live by fresh water, not even a ocean. But let's say I'm at the Y, I have to have goggles on, and when I swim and make air bubbles, then look behind me, I scream. I guess I'm afraid of the unknown, or the endless blue just taking me away. I've had a dream about it when I was a kid. Now I'm scared. Is it normal?
