When all the lockdowns started in March 2020, for a few months people were reporting (me included) that they were having very vivid and detailed dreams. It was apparently due to people sleeping longer, and apparently the dream part happens quite near the end of the sleep cycle that would often be interrupted in people who had to get up early.
I'm still working from home and not getting up any earlier, so I'm wondering why the dreams have stopped. I only just thought of it last night but they probably stopped ages ago.
