Is there a element that shows this pattern of boiling point? Is there a compound that turns to gas at a certain temperature but if heated more turns back to liquid and if heated more than turn to gas? 

Does it exist naturally? Has a such a substance be found? Can such a substance exist? if yes, then why?

Why couldn't at some temperature molecules interact in such a harmony that they actually cling together?
No. If you take a molecular system in the gas state, and you heat it up (at constant pressure), there is no reason for it to go into a denser, more organized state, such as liquid or solid. As you increase temperature, the interaction energy between molecules becomes smaller compared to thermal energy.
