calling all cards

first time caller long time listener.OK to make a long story short i started playing at bodog yesterday.after about 8 hours of play i was calling out turn and river cards like mad and felt i knew my opponents hole cards.i was laying down lots of hands pre and post flop i normally wouldnt have.i felt like i was playing 80%against their rng and 20% my opponents.has anyone had a similar experience?
