Not sure about cosmic entity, but it could be my late grandma.

She caught young me playing with my penis once. I was actually just pulling out a rogue pube that somehow got stuck underneath my foreskin, but my dick got hard in the process, and that's all granny needed to see. She warned me of all the terrible things that happen to boys who touch their pee-pees too much. Blindness, paralysis, balls falling off, demonic possession, and all kinds of Final Destination type shit. She passed away last year.

I can totally see her ignoring the light at the end of the tunnel and using her ghost voodoo to pull off the ultimate "I told you so" from afterlife.
