What is stranger is that I had two different friends that could complete my sentences.One still does.

Identical twins tend to do this; fraternal twins, not so much. Identical twins have the same genetic inheritance, which means they share inherited characteristics (e.g., some personality tendencies and like that) and therefore think more alike than people do who have different genes. Also, twins have a lot of closely shared experiences in childhood - I can see all that leading to a tendency to finish each other's sentences.
