it sounds like your husband may have a sleep disorder. there are sleep disorders in which individuals start to act out their dreams or move about excessively in their sleep. as you note many times this is not terribly bothersome to the patient but can be very distressing to the bed partner and in rare instances dangerous as well. moreover the movements can be a symptom of an underlying neurological condition as well. i would suggest talking with your primary care doctor about this and describing to her/him exactly what he does. if possible taking a video recording of him doing these things in his sleep would be very helpful. you may end up needing to see a sleep specialist.
my husband is talking aloud and giving speeches all while sound asleep. does he have a sleep disorder? . he also moves saying that he was marching playing shuffleboard soccer or even shooting a rifle!
