I find it easier to think of inner and outer senses rather than psychic etc.
I think of it this way: the inner senses show me a 'physical world' by organising information, light etc,
outer senses do the same thing but beyond my five sense world, i.e give me information.
From my own experience both sets of senses are just as real as the other, all of which are simply providing me with information in various forms, therefor there is no paranormal, just unexplored information.
Because I accept information is valid from each set of senses I gain information that is useful from both. Using the terms inner and outer senses just keeps it simple for my own mind!
