I got moved to try Tango when i saw two tangueros melting into each other. That is what I wanted. And after 10 years of dancing Tango, I have experienced that phenomenon maybe 4 times. Perhaps it is called the 'Tango Zone'. It is certainly moving in 'The Zone.' It is what some runners or skiers of powder snow experience when they are totally in the experience, thought-free and moving like the wind.
