One of mine.
A couple years back i moved in with a girlfriend of mine. One night i awoke to a "shimmering shadow" looming over top of me i was paralyzed and unable to move, i felt terrified i kept opening and closing my eyes until the feeling passed and the shadow was gone. My girlfriend was awakened when i shot up out of bed, i told her what happened and i always wondered if she thought i was nuts.
You cannot be physically strong if you are mentally weak.
