Spiders dream represents feeling trapped or hopeless. A negative situation that feels inevitable or impossible to escape. Beliefs about things that you think are permanent or will never go away.
Alternatively, spiders may reflect irrational beliefs. Powerful insecurities that prevent you from doing what you want in life. Irrational fears that prevent you from enjoying yourself, or powerful desires for things you don’t believe you can ever have.
Positively, a spider may represent a positive area of your life that is intricate and patient. Inevitable success based on skill. This would usually be represented by blue or white spiders.
Example: A man dreamed of seeing spiders flood his bedroom. In real life he had an embarrassing health problem and believe it would never allow him to have a girlfriend. The spiders reflected how trapped he felt my his health problem.
