PTSD and dreams

In the last little while, I've read two very different stories where a character who is struggling with PTSD gets help from a dream.

That has got me thinking, could there be something to this idea? Could a dream really help someone like me heal?

And if so, does anybody know a dream walker who could come to my aid?

Because honestly, right now I'm just trying to hold on until I see someone about the PTSD on Dec. 22 ...
