I have a friend who has a terrible fear of dams, water reservoirs, jetties or bridges with big blocks on water; in general, a fear of large buildings on water.
He often tells me that he imagines a dam near the gates and has "anxiety attacks" and becomes very afraid. However, he is not afraid of swimming, or common places with water, like the ocean, pools and so on. On the contrary, he loves to swim.
While he is not afraid of pools, he is very afraid of the wells of the pools where the water enters or where is filtered.
His psychologist doesn't know the name of such a phobia and, after a while, his diagnosis was hydrophobia. The problem is that he is not afraid of water, only these large structures over the water, whose purpose is to control water flow.
How can I get information about this phobia; is there a specific name?
And how can be treated?
