Is There Such a Thing as a Psychic?

So I made an appointment with a psychic. She called the morning of our appointment to cancel because, she said, something unexpected came up. I still rescheduled. Am I crazy?

Is there such a thing as a psychic who can charge by the hour and tell you what is going to happen in your life? I tend to think not. I have had psychic experiences in my life but they came out of the blue. I could not have planned or charged for them, and I felt they were due to my deep connection with another human being.
I believe that there is much more to the universe than what we can perceive through our 5 senses. I also believe that there is such a thing as mental telepathy, where you can transmit what you are thinking and it can be picked up without words, e-mails, texts or twitters. I have had that experience many times with people I am close to.
I also know that if someone is looking at me, I can feel that from across the room. I didn’t perceive it with one of my five senses, but I know it is happening in some other way. When I look over, sure enough, that person is looking at me. How did I know?
So what do you think? Should you go pay someone to tell your future, or are they full of it? Do some people have more psychic ability than others, or do we all have it and just either ignore it, or refuse to believe and develop it? Please share your thoughts.
