How to Draw Dissociation?

As I work on my graphic memoir, one of the things I know I will need to depict is the dissociation I experienced at the moment of my greatest fear.

Dissociation is, in part, "the experience of detachment or feeling as if one is outside one's body" (American Psychiatric Association). 

That is exactly what happened to me. I vividly remember feeling as if I were high above my own body, flying in some sort of hovercraft, like a helicopter or a blimp, watching myself in a great, wooded landscape, far away from any sort of help.

Here is a shot at it.

I am not super pleased with this idea, but of course, it's just an experimental sketch.  

I am building from the sketches I drew of a wooden figure model.  I have no idea how I would depict trees from this angle (you can see me writing notes to myself about this on the page). 

One thing I want to get better at is visual metaphor.  My brain just doesn't think that way...
