Mother Brain

1. Enemy of Samus Aran in the Metroid games "Metroid" and "Super Metroid," Mother Brain is the presumed leader of the Space Pirates and, together with her winged colleague, Ridley, poses a great threat to the Galactic Federation. Armed with her vast intelligence, she seeks to manipulate the power of the Metroids to her advantage.

Typically depicted as resting immobile in an armored case, Mother Brain has also developed other means of defending herself. In "Super Metroid" she demonstrated her combat ability through an enormous bio-mechanical bipedal body- the use of which granted her the mobility she needed to bring her energy beams and bombs to bear against Samus.

Mother Brain was responsible for the slaughter of the "daughter Metroid" of Samus Aran at that same confrontation, adding to the acridness in the feud between the two.

2. an intelligent, reclusive person who remains somewhat guarded and isolated; tends to shy away from those less intelligent than them

brain ghost

A figment of one's imagination which occurs as a result of one's brain filling in gaps in information unnecessarily.

They can be sights, sounds, tactile sensations, or even an uncomfortable feeling a presence. They are distinguished from ordinary hallucinations by the fact that all people are prone to these phenomena, and the person need not believe the brain ghost to represent reality, although some do.
A person's blind spots are an example of a brain ghost.

"I was alone in my house when I felt the presence of a ghost."
"Ghosts don't exist; it must have been a brain ghost."

"I thought I heard a baby crying, but upon realizing that I was alone, I realized it was a brain ghost."
