Dream sequences in TV shows are invariably extremely bad. Dream sequences in movies are usually also bad.

Bad writing of dreams treats them as "easy mode": anything goes, there are no consequences, and it doesn't even make sense. But in good writing, dreams are "hard mode"! Most importantly, the writer needs to justify the dream's inclusion in the story by making it achieve something in a way that's better than a lucid scene could provide. Then additionally, the writer needs to creatively supply their own limits, consequences, order, and coherence, which is genuinely difficult.
