I'm not entirely sure specifically what 'blackkat yyh fanfic' is about without more context. It could be a fan - made fictional work related to the Yu - Yu - Hakusho (yyh) series created by someone named blackkat.
I'm not sure specifically what 'ane x yyh fanfic' is about as it could be a very niche or user - created fanfic. It might be a fan - made fictional story related to some particular characters or concepts within the 'yyh' (presumably Yu Yu Hakusho) universe, with 'ane' being perhaps a character name or some other specific reference within that fan - created context.
I don't have specific information about an author named 'blackkat' in this context. They could be a relatively unknown fanfic writer in the Yu - Yu - Hakusho fan community.
The Enfield poltergeist is indeed a real - life case. It happened in the late 1970s. The Hodgson family, who lived in Enfield, reported all kinds of spooky stuff. Doors slammed shut by themselves, voices were heard that didn't seem to come from anyone in the house. Some people think it was a hoax, but others believe there was something truly paranormal going on. There were even some pictures and recordings made during the time of the events, which added to the mystery.
No, it isn't. Poltergeist is purely a creation of the filmmakers' imagination. It's designed to scare and entertain rather than being rooted in reality.
Poltergeist isn't based on any true events. It's a product of the imagination of the writers and directors, designed to give viewers a spooky and exciting cinematic experience.
