An unwelcome vibe
Take this spooky-Halloweeny if you want, but it could also just be about working with jerks or something
Write about a space you entered and in which you immediately felt unwelcome. Take that any way you want: maybe you took a job and knew on day one it was a mistake, maybe you walked into a party and caught a weird vibe, or, hell, maybe you moved into a place that was haunted af. Whatever the space and whatever it was there that made you feel unwelcome, use that as writing fodder today. Let’s go.
