When much younger, I read the Odd Thomas series. In the first or maybe second book of the series, the titular protagonist encounters some coyotes. The protagonist suggests, when being hunted by them, the survival strategy of making loud, sudden and bold movements and sounds to startle the coyotes into fleeing.

I can’t say whether this would be effective or not, but apparently I took it to heart at the time. Very soon thereafter I was having a nightmare about being chased by coyotes through my dad’s backyard (at the time probably the wildest place I’d been). I took the book’s advice and threw myself forward, yelling. Unfortunately, that was apparently the moment my brain released me from my dream, resulting in me thrusting myself in my then-girlfriend’s then-sleeping face, yelling.

For what it’s worth, I now would recommend avoiding that approach unless actually imperiled in waking hours.

edit: Not to diminish the impact of PTSD. My hope was that the ideally humorous story would raise your spirits. Apologies if it did otherwise. However, I laughed at myself several times while typing the above. Hopefully you enjoyed the anecdote, too.
