The thing is I thought everyone could float on the surface of a lake or river without moving their arms and legs and be completely fine. Better than fine, they would feel very relaxed as the water carried them to an unknown destination.

So I googled my answer and found a few others who could do the same and even a 'wiki how' to teach those who could not perform this miracle. I came to the assumption that this was not infact a weird capability that only I could. I was not one of a kind (in this case) but just dubbed a lazy swimmer. To float completely still on the surface of any body of water is not unbelievable just a case of not swimming and lying on the watery mattress and letting it take you wherever it likes.
