Mystic, researcher, and author Marilynn Hughes made her debut on the  show, describing her out-of-body travels and experiences in other  dimensions. There are many realms in addition to the astral plane, which  is a fourth dimension that overlaps earthly reality, she explained. In  one's first forays out-of-body, you might be jolted by a certain type of  noise-- the vibration of the astral plane, as well as a "rumbling of  voices"-- the thoughts of humanity. There can also be a frightening  sensation of the sound of breathing, which is different when detached  from the physical body, she detailed. Meditation, prayer, and  contemplation are good preparation for handling the out-of-body state,  she added.
By allowing yourself to be guided, you can often learn  more that just wandering on your own while out-of-body, said Hughes,  who noted that a variety of spiritual beings, including ghosts &  lost souls, inhabit a multitude of dimensions. She described her work  visiting hellish realms on rescue missions to pull beings out of  spiritual "bogs." While there, she had to "veil her energy" or subdue  her light in order not to be attacked by negative denizens of these  realms.
The higher realms are inhabited by exalted beings such as  Jesus and Buddha, and a "golden angel from the 23rd dimension" filled  her with a sense of awe, said Hughes, who also described her encounters  with ET beings, where she observed a Galactic Counsel and was  transferred from our universe to a more advanced one for a brief period.

Astral projection (or astral travel) is an  interpretation of out-of-body experience (OBE) that assumes the  existence of an "astral body" separate from the physical body and  capable of traveling outside it. Astral projection or travel denotes the  astral body leaving the physical body to travel in the astral plane.
The  idea of astral travel is rooted in common worldwide religious accounts  of the afterlife in which the consciousness' or soul's journey or  "ascent" is described in such terms as "an... out-of body experience,  wherein the spiritual traveller leaves the physical body and travels in  his/her subtle body (or dreambody or astral body) into 'higher' realms."  It is therefore associated with near death experiences and is also  frequently reported as spontaneously experienced in association with  sleep and dreams, illness, surgical operations, drug experiences, sleep  paralysis and forms of meditation.
It is sometimes attempted out  of curiosity, or may be believed to be necessary to, or the result of,  some forms of spiritual practice. It may involve "travel to higher  realms" called astral planes but is commonly used to describe any  sensation of being "out of the body" in the everyday world, even seeing  one's body from outside or above. It may be reported in the form of an  apparitional experience, a supposed encounter with a doppelgänger, some  living person also seen somewhere else at the same time.
Through  the 1960s and 1970s, surveys reported percentages ranging from 8 percent  to as many as 50 percent (in certain groups) of respondents who state  they had such an experience. The subjective nature of the experience  permits explanations that do not rely on the existence of an "astral"  body and plane.
