The Martian Chronicles

The first men were few. Most succumbed to a disease they called the Great Loneliness when they saw their home planet dwindle to the size of a pin dot. Those few that survived found no welcome. The shape-changing Martians thought they were native lunatics and duly locked them up. More rockets arrived from Earth, piercing the hallucinations projected by the Martians. People brought their old prejudices with them - and their desires and fantasies, tainted dreams. These were soon inhabited by the strange native beings, with their caged flowers and birds of flame.
