Is this real?////////?

I was on omegle.com. They asked if I wanted pics. I said "ok then" as in, wow this guy is weird. Then I got this message that sounded really serious. It said that my IP address was being trapped and that the FBI and police were alerted. It said a letter would be sent to my parents on Nov. 7. I feel sick, I don't think I did anything wrong. Do you think this is just someone messing with me, or am i really going to have to go to court??
