Astronauts report lingering out-of-body sensation weeks after returning from space

Astronauts returning from six-month missions have described a persistent psychological phenomenon in which they feel like outside observers of their own lives. The sensation involves a feeling of watching oneself from slightly outside one's own perspective, and it continues for weeks after returning to Earth. The experience appears to be a notable pattern among crew members completing long-duration missions. Researchers and space health experts are paying attention to this effect as human spaceflight missions grow longer and more frequent.
