Open Question: Why does my cat insist on sleeping in high places, even though he continuously falls down from them?

He always fell asleep in my TV / bedpost (I have a high bed), he kept them off. I heard about every 15-30 minutes to shoot, always happens to be the sound of my cat playing on the floor. Even if this situation persists, he continued to jump right back there, asleep? What is wrong with this cat?
