I did it with Monsters Inc by watching it when I had chicken pox (as an adult), with a bad fever and it seemed relentlessly dark and horrifying.
I've just realised I did it again with the book Interview with a Vampire. I starting reading it when I was ill in bed when I had Covid earlier in the year and there's stuff in there about plague and now I can't pick it up again without feeling totally doom laded.
This is meant to be lighthearted, so please don't post if there is something you find upsetting to relive.
