Had a dream working in an anomalous library tracking changes to consensus reality. I was working on a very bureaucratic procedures update when hypermatter was retrospectively erased from reality, requiring matter and antimatter to now be perfectly balanced from then on.
(Also this justified why the procedures were so bureaucratic in the plot - the only reason I, an inexperienced Librarian, knew about the erasure of hypermatter was because the filing procedures called for the use of it, and I was somehow unable to comply with them)
I said to my dream-coworker “oh god, I won’t even remember hypermatter.”
In memory of hypermatter, which never existed 🥂
