Of course, it is! Re-incarnation strictly means that the human soul-spirit is reconnected to the body after being separated from it. We have enormous evidence of this happening in near death experiences (NDEs).  During an NDE, a person experiences separation from the body and its associated processes (especially pain, but also all sensory links to the body), and usually initially finds himself floating above his body. At the conclusion of the NDE, the person is drawn back to his body and finds himself reconnected as usual. Thus, separation from and reinsertion back into one’s own body occurs.
