Clairaudient: Clear hearing.
As a Clairaudient I hear spirit audibly and also in my head, sometimes in my own voice but at other times in their voices.
Some Clairaudients only get the odd word spoken to them but I am lucky enough to hear full sentences and answers to questions I might ask!
Clairsentient: Clear feeling.
Clairsentients can feel people from the spirit world around them even if they are not showing themselves to them.
Claircognizant: Clear knowing.
This is knowing something before or after it has happened, when I get this I just know that it is right and feels so real as if I have witnessed it.
