I’ve watched a lot more Twilight Zone than I have Outer Limits, but I’d say that Twilight Zone frequently has surreal/bizarre situations that can be practically anything as long as it’s a weird tale. So it could include the things you mentioned, but often an episode reveals that the world, universe, or situation is very different from initial assumptions (by the audience and/or characters). That can involve dystopian futures, apocalyptic situations, curses, fate, afterlife, “other dimensions”, time loops, and/or the characters are actually toys or robots or whatever.
As far as I have seen and remember, The Outer Limits tend to be less surreal and more about space aliens and futuristic technology (science fiction) and situations with those elements, rather than TZ’s situations which were more frequently about other freaky universe settings.
