All birds are to be considered messengers from higher consciousness and other dimensions.
The blue jay specifically is one of the more talkative birds, so its meaning connects with communication. Its blue color aligns it with the throat chakra, further emphasizing this communication sensibility to the medicine that it offers. When the blue jay visits you in dreams, it is time to take a powerful look at how you are communicating.
