The episodes you have described are unusual. They are not characteristic of delusions associated with schizophrenia but that possibility cannot be ruled out. Another possibility is dissociative identity disorder. Dissociative identity disorder is a psychiatric condition in which an individual claims to have at least two separate and distinct personalities. There may also be a medical explanation. It’s important to rule out an organic cause.
Individuals who claim to have psychic abilities report an experience similar to yours. Their experiences would be termed paranormal. I use the expression paranormal to mean something that would be difficult to prove scientifically. Individuals who claim to have psychic abilities or who claim to be a medium (an individual who speaks with the dead) describe having similar experiences. Mediums, in particular, have described the experience of “channeling” another individual, usually someone who is deceased. When they are “channeling” the deceased individual, they may claim that the “spirit” temporarily inhabits his or her body, usually to communicate a message. During the channeling process, the medium will often claim to have the deceased person’s thoughts and feelings. They have also described feeling exhausted after that experience. It is difficult to scientifically prove whether or not those abilities or experiences are real. If you are interested in learning more about the scientific validity of mediums, you may want to read The Afterlife Experiments: Breakthrough Scientific Evidence of Life After Death by Dr. Gary Schwartz. Dr. Schwartz claims to have performed randomized, controlled experiments with mediums claiming to receive messages from the dead. There was also a HBO documentary created based on his experiments. None of these claims have been proven scientifically.
You don’t think that seeing a physician would be very helpful but I believe otherwise. You should be evaluated. A physician is not going to manufacture a problem. If there is a problem and it is found that would be good because then it could be treated. That’s why an evaluation is an important first step. I hope you consider it. Thank you for your question.
