Disembodiment is a liminal state, not dead but not really alive, the life of a phantom, a walking dream, without roots or ground.
To be disembodied is to identify with every stray thought and errant mood that comes along, and cling to it, like a drowning man at straws.

outsiders, rebels with a cause who have upturned the mulch of our dead

dislocation. Free-floating between old worlds and the new, guided only
by the shining paths of mother evolution. We have passed over, we have
passed the point of no-return and since there is no turning back, we
celebrate the momentum lifting us on the wings of perception, grace, and
whatever skills we have earned from surviving the inevitable
catastrophe of self. Only when we are over, does our real life begin.” —
