The Fantasy is the Reality of the Mind
I think this one is called Altzheimer. I know that cuz my deceased grandma had that and did all sort of craziness. She gradually forgot everyone until I was the last one she forgot. If that's not Altzheimer, that's known to hit mostly old people, and rarely young people, then idk what it is, tbh.Met her a few times and everytime she did not know who I was even though i met her the day before. My aunt had the same thing, she couldn't remember my name or place me...and she used to know who i was for years. Her personality changed as a result so they had to keep an eye on her.
Speaking of BBC, I won't talk about this. I'll leave that to the rest who experienced him.
