Many of the same people engaging in the health and sanitarium movements were also attracted to popular physics and mediums, and new religious groups that supported the use of psychics and mediums, such as the Theosophists and the Society for the Diffusion of Spiritual Knowledge.

The Fox sisters, with the help of their Quaker friends, were largely responsible for the birth of the American “Spiritualist” movement.

I’m sympathetic, I suppose, in that I imagine these intelligent and religious people in a rapidly changing world, obsessed with the novelty of scientific observation and technology, seeking to blend two worlds together. If one firmly believes in a soul and an afterlife, certainly one would want to use the new and exciting scientific methods to prove those things exist. Visitors to mediums like the Fox sisters often called themselves “investigators”(much as “ghost hunters” do now). It was a pastime of the rich to play scientist in the world of ghosts, and to try to find, with all the proper witnesses and documents, the best possible proof of the existence of ghosts. Combine those beliefs with the grief that follows the sort of young death that was rare enough (compared to even 100 years prior) to be somewhat unexpected and tragic but common enough to create a huge market of young grieving mothers and fathers and widows/widowers. It was very easy for two groups to find an audience with these people; the well intentioned but deluded, and hucksters. Sometimes, between these groups, there were grey areas. Lie long enough, you’ll start to believe it yourself.
Psychics who were simply seers, giving straightforward predictions of the future or messages from the dead were out of vogue. Audiences didn’t just want answers and comfort, they wanted a show. If you were going to be rich and famous post the Fox sisters, you needed to bring something new to the table—something frightening and entertaining.

There are many different kinds of psychic ability, you see. A medium in the Victorian era helped him or herself acheive greater fiancial success if they could develop several of these skills. These types of “psychic ability” became popular and were named at different times. So I’m using the modern names, and will try to highlight those that are particularly popular among Victorian audiences. I gathered these from a few different sources, and the list isn’t complete I’m sure.
Astral Projection – The ability to leave the body in spirit form and travel somewhere else. This is handy if you are finally settled into bed, but suddenly realize that you may have forgotten to lock the front door. You can go check in spirit form, so you don’t have to waste your time getting out of bed right after you’ve settled into a comfortable position. If you’re really good at it, you could in theory lock the door.
Aura Reading – Reading Auras.

Channeling – This is the ability “mediums” use to allow the dead to vocalize through them. There are two types of channeling: direct voice, which employs psychic ability to give the spirits the power to speak somehow, and trance speaker. Trance Speaking is the most well known form of channeling, as the medium allowed the spirit to use the mind and body of the medium to speak. Some psychics took this as far as claiming temporary possession by a spirit. This was very popular among Victorian audiences, and of course very easily faked.
Clairaudience – This is tricky. It is the ability to hear the immediately inaudible. For instance, the psychic can hear a conversation taking place miles away. Psychic eavesdropping.
Clairvoyance – The ability to see things obstructed from view. Clairvoyance is not the ability to tell the future. Clairvoyants can see things in the physical world that are at a distance, behind a wall, under the bed, etc etc. This was a common ability claimed by Victorian psychics.
Clairsentience – The ability to sense thoughts/feelings/memories in another. If you forget where you put your keys, a Clairsentient could recover the memory, or sense how sad you were about losing your keys.
Divination - Fortune telling and other attempts to predict our AMAZING FUTURE. The reading of taro cars, etc, falls into this category. This has been popular for thousands of years, ‘cause everyone wants to know about the future!

Empathy – Like Troy on Star Trek TNG. You can sense the feelings of others.
Intuition – Women have it, I’ve heard.
Levitation – Look at you! Way up high! In the air! In the sky! You are the luckiest boy in the world. This was much appreciated by victorian audiences.
Mind Over Body – I’m keeping this on the list because of the influence Buddhism had on Theosophy and other branches of Spiritualism. It’s basically the ability to suppress one’s own thirst, hunger, exhaustion. Some people consider this a psychic ability.
Precognition – Seeing the future! But on your own, not through divination, and usually only a little bit.
Psychometry/Materialism – The ability to touch an object and sense events, people, feelings, locations, etc the object was associated with.
Pyrokinesis - You can start fires WITH YOUR MIND! I doubt this would have been popular in any firetrap victorian house.
Telekinesis/psychokinesis - Moving objects using your mind. Very popular with the victorians, a neat "parlor trick."
Telepathy - The ability to communicate with another person with your mind, but without your mouth.

One of the best and most convincing of these performers was Daniel Dunglas Home (March 20, 1833-June 21, 1886), a Scottish emigrant descended from a line of “seers,” for whom psychic ability may have taken a back seat to more impressive feats. He thought happy thoughts (probably…I think that’s how it works) and flew.
Home was a clairvoyant, he channelled spirits, he dabbled in telekinesis, and he levitated like nobody's business. Because we don't have photographs or videos of these levitations, it's difficult to say how he did it exactly. He certainly had assistants, and typically performed in dimly lit environments (despite his own declaration that all seances should be performed in the light.
Home was the author of a handful of books, including an autobiography which you can get online on google books titled "Incidents in my life." Home was one of a number of psychics who saught to debunk the work of others in his profession he believed to be frauds. Home did not believe, according to his book "Lights and Shadows of Spiritualism," that spirits could be called forth and manifest in a solid form. Florence Cook, for instance, a young British medium who became famous in the early 20th century, claimed to be able, once conveniently hiding in a closet, to be able to call forth

Home also believed that seances held in darkness left too much opportunity for trickery. Yet, of course, Home too kept the lights low.
I'll be reading Daniel Dunglas Home's books, and passing the savings on to you. I'll also ramble a little about what psychics and magicians intersect.
