And.. Alex's biology explain of ghost and other sprit -__-

1. normal one.

Normal ghost are floatable, change form, pass a wall. Their age is infinity so the atom in their body had to move at very high speed to change form and float in oxygen. Their body probably made of Helium. Since they body seem to immune to fire and gun.

2. Zombie

In biology, Zombie like a Hydrophobia dog. Agressive and tend to attack same species. Zombie probably undead. They is just human who lose their mind and attack everyone. And if you shot them, they die :P

3. Vampire

Most vampire is very old age. If vampire are real, and first shown in 15th century. All human would turn to vampire or dead in 1 month. So it cant be real.

4. Werewolve (and Hulk..)

Transformation from human at 6 feet to larger object is possible. But at object increase size, pressure and tempurate will decrease. Their blood will be suddenly boil. Blood will be unable to feed oxygen to brain. And lead to dead (just like human without suit in space)

5. Witch? Just a old ugly woman who learn cast and spell. Just like Heromine (from Harry potter) at 90
