You shouldn't be starved or "thirsted" to death. When one reaches terminal illness time, organs gradually lose normal function, appetite diminishes, consciousness delclines etc. Good Drs administer IV fluids continuously, pain and rest meds as needed to keep you comfortable and small oral feedings you want and tolerate. What you have seen here is a healthy body, suddenly having everything withdrawn and the "beautiful" result.
