You had the dream, it is your duty to understand it. Nobody else can tell you what hidden message is in that symbol because It's personal, just for
you. Meditation might help.
Once you understand the message in your dream, you decide who you want to share it with.
Did your dream involve Egypt? A Goddess/woman figure? A book? A horse (white)?
Just curious...
My mother describes a lady she see's in her dreams, that offers her a ring with a right side up triangle and a sideways triangle ontop of it...a 3d
ring.
