I need to know if this is normal

Okay so everytime i read something a bit intense (for example dark heaven) i have to take a break.

and its not because im triggered by anything (at least i dont think i am...cause i can handle reading a whole bunch of stuff and have read things that had worse stuff in it just fine)

but i get sooo much anxiety about whats about to happen next. like its so bad i get super overwhelmed and i have to pause the story (and not even for a day but like i literally bookmark it and remove it and read it later, like maybe months later. it depends on if i remember to do so or not)

idkk maybe i am triggered by smth, but ive read many things similar to dark heaven and ig it "doesnt get to me". i think im too immersed into the story but idk

just wondering if this is normal tho lol
