A while back, I watched a Korean drama called Twinkling Watermelon, which is about a high schooler who goes back in time and meets his dad when he was also in high school. After finishing it, I dreamed that I met my dad when he was around my age, but it turned into a sex dream. It wasn’t necessarily the most absurd, grotesque, or unhinged dream I’ve ever had, but it was definitely the wildest in my opinion because of the implications.
I once had a dream that I went with my family to visit an old family friend (not seen in years) for dinner, but they lived in a different (i.e fictional) house that I had never been to before. Normally this wouldn’t seem strange but when I woke up and told another adult family member, they looked completely shocked. It turns out they had also dreamt of this exact same scenario that night set in the same fictional house. We could describe the setting and events in detail and both had exactly the same experience but from different perspectives in the dream.
I have no doubt there is some psychological explanation for this phenomenon but regardless it was quite an interesting experience.
