There were not enough time to get anything at all, not even your phone, keys, or wallet, you have nothing besides your clothes and any disability aids (like glasses, hearing aids, etc.). Anything that can’t sustain one hour of burning will be destroyed. All living beings are safe.
Things to thing about: money, sentimental stuff, journals, books, hard drives / digital data, and all of the time and effort you spend organizing your bedroom.
Most important thing would be pictures and mementos honestly, but most of my stuff lives at my parents house because I do not have any space, so I guess some stuff would be safe.
Of course I’d lose electronics and gaming stuff too but that feels more replaceable than my other things.
Also would probably kill me to lose my cat’s ashes.
