Do you not have a bug tracker or ticketing system of some sort to manage these things coming your way?
Incredibly few people at my work get much more than dismissive small talk from just walking up or from sending me a message expecting me to re-prioritize everything else for their special pet problem.
My manager sets my priorities, any changes to that need to come from him. They can take it up with him if they don’t like it or disagree.
I don’t respond to IMs or emails not from my boss or from my own team except when I’ve hit a mental road block and need to think about something else to refresh.
And I don’t actually work on any of those requests until there’s a ticket in. If someone comes to me asking why my main job duty isn’t done, I’m sure as hell going to have a paper trail documenting who fucked up the timeline. No ticket, no work.
That also puts some weight on anyone else able to pick up tickets for your team to do it, so it’s not always falling to you because you’re not jaded enough to say no.
I love eldricth horror precisely because of this. Imagination will almost always be scarier than something that can be put into words. Descriptions give handles to hold onto for your understanding, boundaries and walls for the horror to fit in.
Give me more vagueness about how, gazing at it, the room could not have possibly contained its size. The feeling of the split second while tripping before you connect with the ground, stretched into an interminable constant in the back of your mind.
