The body image is altered not only in psychotic disorders but also in religious experiences.
Yuasa says;
In satori, there is no distinction between the body of oneself and others, between the body of a person and the Buddha. The body is changed into, as it were, a metaphysical body, and it loses all its objective characteristics found in the everyday dimension.....The distinction between one's own and others' bodies, between being a self and the being of others, completely disappears.

Again, having my own body, is not a matter of course!
