It depends. There are different opinions on whether the Couch Story is true. Some believe it is based on real events, while others think it might be fictional.
I think 'couch science fiction' might be science fiction media that is best consumed in a laid - back, comfortable setting like on a couch. This could involve things like science fiction shows that have a lot of action and adventure elements but not overly deep philosophical or scientific concepts. It could also be some short - form science fiction stories that are easy to pick up and put down while you're sitting on the couch, perhaps during a commercial break or in between doing other relaxing things at home.
Honestly, I have no idea what the Vance Couch story is. It could be a personal account, a historical narrative, or something completely made up. We'd need more information to know for sure.
Picnicking is also a wonderful option. You can find a nice spot in a park or by a lake, bring some food and drinks, and just relax outdoors. It doesn't require much skill or equipment.
