Brilliant movie! Parapsychology is the study of paranormal and psychic phenomena. Although many doubt these human abilities, I strongly believe that there are those with gifted mindsets who have powerful sensing abilities. Senses that go beyond one's sixth sense! In my opinion, all humans have the ability to truly connect with this world and thereby heighten their ability to sense what cannot be viewed with the naked eye. Just like air particles, earth's magnetic fields, or even pathogens in the atmosphere, there are atoms that cannot be seen with the naked eye. I empathize with those who have such insight into other people's pain and suffering. To be able to feel that level of intensity over and over, every day and every hour, by itself is traumatizing. Such persons may suffer from manic depression. In the end, when they showed him alleviating his daughter's suffering by injecting a drug into the saline cap, I completely understood why he did what he did. From a psychology perspective, I would like to emphasize the importance of grief counseling. When a family member suffers from a terminal illness, the other members will be exposed to some level of psychological distress. Some mismanaged distress may lead them to extreme circumstances of killing the one who is in deep pain. It is important to identify this at the onset and treat all family members by preparing them for what is to come, "hope" in all its form of subtle existence etc. I loved the movie.
