Pathetic Fallacy is a more specific type of personification.

Pathetic Fallacy consists of giving animals and inanimate objects human feelings.

For example:

"The angry sea"

"The clouds are crying"

"The sad cold night"

while personification is just giving any type of human qualities to animals or inanimate objects.

For example:

"Lightning danced across the sky"

"The car complained as he turned the key"

"She heard the last piece of pie calling her name"
