In BIONICLE, Tren Krom tends to inflict this when he searches someone's mind for information, as it also gives the victim glimpses into Tren Krom's mind. The fact that he tends to assault his victims with his long, red, fleshy appendages while doing this only adds to the disturbing subtext.
Toa of Psionics are also capable of doing this, and it's implied that they can cause permanent brain damage with their powers.
The Makuta species has many mental powers, too, and where a Toa of Psionics may stop, they will gladly push further. When Teridax unleashed his powers on Karzahni's mind, it reduced the latter into a vegetable on two legs. Yet Karzahni was the one most famous for his soul and mind-crushing visions. Makuta evidently like beating others at their own game.
Gali Nuva experienced one after being hit by Dalu's Sensory Overload-inducing weapons. Her sight became so advanced that she actually peered into other universes, all of which she just couldn't take in at once, and eventually broke into a furious craze, attacking her partners and running off into the wilderness. Thankfully, Axonn was there to cleanse her mind with his healing powers.
