Whenever I look into or at anything dark my mind imagines a fully formed creature or creatures and will literally move and come towards me, and the only way I have to cope with that is a sleep mask that makes my vision blacked out and the monsters are all around. But after a while I learned that I could sometimes make them go away but another one replaced it after a while. I have now learned to conjure imaginary fist that punches them in the face. It helps but they still come, and I can’t sleep if my door isn’t completely shut or there will be fingers curling around the edges all creepy like. I’m sorry, you probably didn’t need to know that, but I need to unload it.
