The best way I can describe aura's I've had in the past would be like how you feel when you get morphine for pain in the IV & I've had it and if anyone's ever had that, you know what I mean.
First time in hospital, after waking from surgery, I didn't ask for pain killers for the first 12 hours after waking, I just wanted to be awake, knowing I was alive and made it through surgery but when I did ask for pain killers, they gave me morphine for pain and good thing I couldn't walk cause it made my vision "literally" bounce. Felt like someone had taken my eyeballs out and shook them up and put them back in. lol
I felt no pain but the instant reaction was intense and very weird
