It's important to know that the free psychic chat rooms are not for receiving free readings. The free chat rooms are for you to get to know the psychics before you invite them for a private reading. But that being said, it is totally possible to get a free answer or free reading during a free chat. There are many psychics who offer totally free psychic answers on a regular basis. 
Senses used by mental mediums are sometimes defined differently from in other paranormal fields. A medium is said to have psychic abilities but not all psychics function as mediums. The term clairvoyance, for instance, may include seeing spirit and visions instilled by the spirit world. The Parapsychological Association defines "clairvoyance" as information derived directly from an external physical source.[37]
