From the information I have got it is noted "A ghost is a human being who has passed out of the physical body, usually in a traumatic state and is not aware usually of his true condition due to trauma, is stuck in our physical world and needs to be released to go on." An intelligent haunting means that a ghost, or disembodied voice, will try to communicate with you directly. They would speak to you, or stop and seem to look directly at you, or even touch you. In some cases, they would respond to your questions, and actually do what you ask them to do. At times, these can be as real to you as if you were with someone in real life. In this type of haunting, ghosts will absolutely try to get you to notice them if they feel the need. Most ghosts have something to say, and want to speak to those willing to listen. Random voices to us mean that we haven't taken the time to investigate properly. If ghosts speak at all, they are serious about communicating, and we must give them the proper time to do that. Some people can actually see ghosts while others can't.
