non-lucid

2 nights ago i was in a nightmare were i was about to be killed, i was about to manually awaken myself as i do in this type of situation in nightmares, but instead i stayed in and looked at my hands as a reality check, and it look as if my hands were all reflected by mirrors as there were loads of reflections, then i appear in this room with 2 of my friends, i remember looking down at my hands again and i had 20 fingers on each hand and i knew that i was dreaming, however i thought that my 2 friends were also lucid dreaming and could control everything.... and i did not really take controll, i just "knew" i was dreaming, but i also thought that my friends were real was this a lucid dream?
