Oohh nice! No, you did well. You were starting to dream already, your body was falling asleep and you were still aware so you noticed the transition and vibrations. You may have hallucinations which can be visual, auditory, tactile, etc. and the forces you felt were most probably tactile hallucinations (those that are felt). These are all normal and nothing to worry about. Next time it happens, just focus on the dream and visualize it, and remind yourself that you are going into the dream. It just takes time and practice before you get the hang of it but it was a very nice attempt
