A childhood belief about bathrooms

In our childhood home, the bathroom door was located directly across from the basement door. When I was 6 years old, my sister (9) told me that when I flushed the toilet a killer whale would come out and eat me, but if i didnt flush it the pee-pee monster that lived in the basement would be waiting for me at the top of the stairs to take me away. However, the pee-pee monster was scared of the light so he wouldnt come out if we laid a flashlight at the bathroom door pointing at the basement. My only hope, according to her, was to point the light at him, flush the toilet, and run away from the killer whale as fast as I could. The funny thing was...she wasn't being mean to me, she honestly believed it herself and was only attempting to protect her lil bro from the "bad things" lol
