I read an excellent SF short story about 20 years ago. It started as a man being chased by the police. The man himself had had his mind taken over by another 'being'. These 'beings' were hunted by the authorities. At some point the 'being' jumped to a new host and mentally battled with the host mind for control of the body. The 'being' thought that the host's minds were destroyed during these battles, but as the 'being' got into danger of being caught by the authorities, the previous host minds talked to the being, telling it how to escape.
The twist in the story was that the the host minds actually enjoyed riding along with the 'being', as they got to live and experience things far beyond what they would have otherwise.
