Islamic Interpretation of Dreams (Ibn-i Sirin):
(Hairy spider; Spider) A tarantula in a dream represents a loathsome and an evil woman who interferes with peopleâs business and damages their interests, or who destroys what they repair and denies having anything to do with their sufferings.
In a dream, this interpretation is based on the legendary nervous disease, formerly believed to be caused by a poisonous bite of a tarantula.
Thus, when this harmless hairy spider is seen in a dream, it also could represent a lethal enemy of a fierce sting, scowling, or a despising look.
