According to Jungians, the general interpretation of insects in dreams closely follows the way they are perceived in real life: as irritating and potentially dangerous creatures that often attack in great numbers. Some insects do, however, have qualities we can admire and although still able to annoy us, they can set a helpful example when they appear in dreams. Use your common sense and some general impressions about the specific insect when interpreting your dream. For example, if you dream about bees stinging you, think about some of your relationships; if ants appear, then consider you social interactions and work ethic.
If you dream about wasps, are you in some kind of danger? Bear in mind, though, that dreams featuring insects are generally warning you of some poisonous or dangerous influence in your waking life.
Insects can also represent irritating, small problems in daily life with which you feel powerless to deal or feelings you would rather do without. These might be feelings of guilt or regret, or something that you cannot quite recognize tugging at your conscience. More often than not, insects represent negative feelings; they can symbolize how life requires you to form a brittle shell; they can also sometimes completely replace your own body, as in Franz Kafka’s novella Metamorphosis.
Arachnids—here comprising scorpions, spiders and ticks—often have a different symbolism; many people suffer from severe phobias for spiders in particular.
If you are fearful of spiders in the waking world, they will quite often simply represent something of which you are terrified in your subconscious.
