"Psychic-Powers"

Is there anything called 'psychic' exists? I am very fond of people who fall under this category. And surprisingly once in my lifetime I felt that power within me. I felt out of the world; as if I found inner peace and attained a level of spirituality that a normal human would fail to reach. I was powerful and the feeling scared the hell out of me. I thought I was God. I don’t know who God is. I don’t know how it happened and why it happened. I was scared, really scared.  Gradually I believed these powers are a curse to me for any act of a sin I did may be some day. I could have utilized it but I did not want it. I wanted to be normal. May be it was not a power but some mere stupid coincidence happenings that led me to believe so.
