Narrative:
My flight departed dfw airport. We were handed off to departure at 1000 ft MSL. On the initial contact, the departure controller gave us 'climb to 8000 ft.' as we were climbing through 6400 ft MSL, the controller asked us our altitude. We advised him we were climbing through 6400 ft to 8000 ft. He responded that we were given 4000 ft. I reported that he had given us 8000 ft. He told us to descend back to 5000 ft. There were no conflicts with any other aircraft at any time.
