i had a dream last night that a had some gifts for my friend, one of which was a beautiful necklace. I was in the interior of a house, a long hallway that was somehow jagged or difficult to walk through. I saw my friend and immediately read her mind, (she wasnt thinking very good thoughts.) so i decided to keep the gifts for myself. I put the necklace on and it became transformed. a long cylindrical piece at the middle started changing colors according to my mood , blue, yellow, pink, green etc. I became good at controlling the changes. i dont remember the rest of the dream but i think i was avoiding someone.

i know the necklace itself has to do with the 5th chakra, will and self-expression.
any ideas about the changing colors?

thanks
