What does it mean to dream of a spider that's orange with black dots?

Answer 1

This sounds like it might be a male Ladybird Spider. See links below for description and photos. The dreamer might easily have seen some news report or magazine article about the spider without consciously remembering it, while the subconscious mind stored that information.

... This particular spider is quite endangered, which might have some significance for the dream's meaning. The dreamer might feel "endangered" or threatened or feel forced to be someone he/she is not.

... Alternatively, if the dreamer is a gamer, or spends time near someone playing World of Warcraft, the spider in the dream could have been triggered by one of several creatures - Spiders or creatures resembling spiders - with variations of orange or red with black markings. In this case, the dream would be a simple nightmare with the monster standing in for whatever causes the dreamer anxiety.

Answer 2

Orange and black worms might be Wooly Worms that old folktales claim predict long-range weather conditions by the relative size of color bands. But what the worms mean in your particular dream depends on the emotional tone of the dream (happy, sad, threatening or hopeful,) where the worms are, what the worms are doing, and so forth.
