The spider, in general, is a strong dream archetype. For the ancient Greeks, Arachne was a weaver who challenged the goddess Minerva to a weaving contest. Although Arachne was skilled, her story suggests that mortals pay a price for thinking they are as good as the gods: Minerva transformed Arachne into a spider.
In the Celtic culture, prisoners learn patience and persistence from the spider, which rebuilds a web every time it is torn down. For Native Americans, the spider is associated with history and is a link to the future. In India, the spider is thought to weave the web of illusion and is associated with the moon and the alternation of birth and death.
The spider is a nearly universal symbol of Fate: a teacher, a destroyer, and a trickster.
Dreaming of a tarantula suggests that you are surrounded by enemies who will bring you some type of loss. The dream tarantula may also symbolize the “dark” side of your personality or predict poor health or a disappointing love affair.
A spider (tarantula) dream usually symbolizes someone in your waking life who is sneaky and cruel. It could also represent someone who is smothering you. The dream spider may be telling you that you should become more self-aware as well.
A tarantula dream is a significant and spiritual dream that is encouraging you to investigate the meaning of life. The tarantula suggests that everything is connected and that you should be more strongly aware of how you fit into the world.
As in all dreams, the feelings you have about spiders influence the meaning of the symbol. If you fear spiders, the tarantula will have negative associations, such as being trapped in a bad situation. If you view the tarantula as a symbol of connection, it will mean that you should integrate yourself into your environment.
The dream tarantula could also symbolize the number 8 in a dream or be linked to hidden fears. If you kill a tarantula in your dream, it means you will succeed after suffering through a period of bad luck.
