What does it mean when you dream about blue strange people touching you?

Answer 1

This dream might very well reflect the popular movie "Avatar" with the indigenous blue people of Pandora. Symbolically, one possible interpretation could be the dreamer's realization that one's life is "touched" or effected, by many people who are complete strangers. For example, our electronic devices, our clothing and even our foods are produced by unknown laborers in different lands around the planet. Alternatively, the dreamer might feel surrounded by persons who treat him/her as a stranger.

Answer 2

One possibility is that the dream was triggered by watching television or films with blue characters, such as Avatar or the Blue Man Group (see link below.) Another possibility is that the dreamer feels sad or depressed which is often referred to as "feeling blue." Yet again, the dream might refer to the style of music called The Blues and the people who create that music.
