Can you explain or describe what it's like to have your 6th sense/psychic abilities?

I was asked recently to describe what it's like to be psychic, but all I could muster up was, "It's like having your sense of taste, you just have it. You can't describe the experience and what you "know", rather, taste."

Sure I can go into what I see or what I know if given a question, see a pic, etc...but I just had the hardest time being able to find the words.

Opinions?
