How do we identify a person with Hallucinations ?

Hi friends, have you ever heard the term hallucinations? What is meant by hallucinations? See, suppose we are imagining that there is something like ghost or whatever it is and if we feel they are really present in front of us, it's only illusionary, it is only our imagination. When imagination is materialized, we feel the presence of those things in front of us. That is what is known as hallucinations. Not only that, sometimes we hear some sounds, unknown sounds, actually those sounds are not bad, we feel hearing those sounds that also comes under hallucinations. People suffering from hallucinations, sometimes they hear the sounds of footsteps, banging of the windows, window panes. Sometimes they hear street music. See friends, now let us have a small discussion on imagination, illusions and hallucinations. What are the differences among these three terms? Imagination is something which is going on within our mind, it happens in our mind, right? It is not visualized, nothing is visualized, so just we are thinking and it happens only in our mind. That is what is known as imagination. Perception, based on our perception, if something appears as something else, then it is called illusion. For example, if you see a snake or if you see a rope and if the rope appears to be as a snake, that is simply illusion. So this is wrongly perceived, this aspect is wrongly perceived, that is illusion. Not only that, sometimes whenever we are travelling in a train, we feel, actually train is moving, but we feel the trains are moving backwards. When we are moving forward, the trains appear to be moving backwards, that also comes under illusion. There is one more term, delusion. What is the difference between illusion and delusion? Illusion is not mental disorder, but delusion is mental disorder. Based on this aspect, we have an interesting story, let us know about it. Once three friends were discussing on mysterious incidents happened in their lives. There was a stranger listening to them with some enthusiasm. One of the friends asked him if ever any such incident happened in his life too. The stranger said that some mysterious incident happened in his life too. He started narrating it. I recently shifted to a house. It being old, there are many patches on the wall. My attention was caught by a patch which just appeared as human face. I felt there might be someone in this world resembling the same features of the contour. My search began to meet the person of similar features of the face on the wall. People considered me lunatic and it is my delusion. Finally, I found the man with same features. I asked his name. He said Armand Wall. I was shocked to hear this since the street where I lived is Armand Street. The face on the wall started fading. I thought something might have happened to that person named Armand Wall. The next day, I found in the newspaper, multimillionaire Mr. Armand Wall's death in headlines. Again, I looked at the wall. Face on the wall completely disappeared. There are three mysterious things happened in this story. Can you guess what they are? Of course, it's a story made up by the author. But these things happen in our lives too. What do we call it friends? As the author actually made this story, it's only his imagination. As the face appears as the face of a human being, it is illusion. Thinking about it continuously, having the feeling that some person is existing in this world is delusion. Finding the same person with same features may be hallucinations. If it really happened, then we can say it's a mysterious incident that had happened in his life. Let's come with some other interesting aspects in our next video. Till then, bye.
