Can Muggles see Dementors under any circumstances?
No. Muggles cannot see Dementors under any circumstances. They perceive only a sudden, unexplainable drop in temperature, blinding darkness, and intense psychological despair. Squibs can sense their physical displacement, but true non-magical humans remain entirely blind to their physical form.
Can a Dementor be permanently destroyed with magic?
Standard offensive magic like the Killing Curse (Avada Kedavra) or explosive spells have zero effect on Dementors. They are amortals: entities that were never truly alive and therefore cannot technically die. They can only be driven away using a Patronus Charm or starved into diminished numbers by removing human sorrow and misery from their environment.
What is the biological impact of the Dementor's Kiss?
The Kiss consumes the victim's soul through the mouth. The victim's heart, lungs, and brain stem continue to operate, but consciousness, personality, memory, and spiritual identity vanish permanently. The target becomes an empty vegetative husk incapable of recovery.
