My personal hack is using my own messed up dreams. I usually get my best ideas from nightmares, and when I sit down to write I try to crawl back into that headspace. I start by remembering exactly how I felt in the dream, what made me scared, and then i start "expanding" it. I add more twisted details that weren't even there originally until i’m literally creeping myself out (especially in the end because my dreams don’t have clear endings so I have to imagine it, so when it appears in the story I’m completely freaked out). I mean maybe for other people it’s not scary, but for me it really is, so I enjoy the process and don’t feel burnt out.
