I dreamed of a bodhisattva and gave me a necklace.

Hehe, it's okay, which shows that you have high consciousness and know how to pursue truth.

Buddha should embody the image of wisdom and morality in his dreams, and pendants may indicate some kind of conceptual guidance in real life. Bodhisattva clears your sins, maybe you do have the idea of "one good turn deserves another". This is a good dream, which can play an extremely important role in self-psychological suggestion and play a very important role in psychological maturity and social viability.
