stl2020,
It is not uncommon for people to incorporate things they have just experienced (movie, TV, reading, actual event), into their dreams. This is why people with PTSD have many terrible nightmares.
It is also not uncommon, if the TV in currently on, for whatever is going on in the show to be incorporated into a dream. Just as sometimes, when the phone rings or the alarm clocks goes off while you are asleep, it may not be recognized for what it is, and be placed into a dream sequence, or you may answer the phone if the alarm clock rings.
My child used to act out dreams. If there was fighting, arms and legs would swing. Fingers would be pointed and shooting sounds made. Occasionally, when swinging, other people would be hit. Unfortunately, it was not outgrown.
If this starts to become a problem or you feel that you may be dangerous to your spouse, you should probably see your physician about it. Sometimes, sleeping medication can help, other times just speaking with someone about it can help.
Good luck.
