@NavaMxm Hii I don't know if this could work for you as well, but when this happened to me, i would open the note app on my phone and jot down the plot idea/the scene i came up until it was completely burned out of my mind, then close the note forever until i have another idea
I have reached max word capacity in two notes because of this XD
And, well, if one idea doesn't leave you alone, is too elaborated (like, has a whole outline and stuff) and has got you writing a good chunk of words, I guess you could transform it into a oneshot (definitely wouldn't pass up on reading more from you)
This is just a suggestion, take care not to burnout <3
