I've been dreaming about someone I haven't seen in a really long time. So I wanted to know what these dreams ment and I consulted I ching. I got Hex 53 lines 3 and 5 chaning to hex 23.

No hexagram 23 doesn't scare me really but Its kind of vague...The only thing I getting is that our friendship with this person is dying...Or that is going to end.
And about hex 53....Well I have no idea what that means.

It suggests a longing to meet with this person again, as there seems to be a sense of emptiness inside you due to this separation for so many years.

emptyness indeed.
