Yet there are several dreams that are nothing like that. Lucid dreams are dreams by which you know at that time that you are fantasizing. That they are not the same as ordinary dreams is obvious once you have one. The experience is something similar to waking up in your own dreams. It is as if you “come to” in order to find you are dreaming. Lucid dreams was previously a topic within psychical investigation and parapsychology. Perhaps their incomprehensibility created them good candidates to be thought paranormal. More lately, however, they have begun to look in psychology journals and also have dropped out of parapsychology—a good example of the way the field of parapsychology shrinks when some of its subject matter is really explained.
