Etherealization

Deadliest catch without the crabs

How traumatic is hitting the back of your head so hard that you almost black out and can't pick your head up off pillow for almost 2 weeks? A couple years ago I fell snowboarding as I went thru a patch if pure ice. I ended up rolling back wards and all of my 25-30mph of momentum was stopped by the back of my head. I don't really feel that different but maybe I am.?
